fgetcsv -- 從檔案指針中讀入一行並解析 CSV 欄位
說明
array fgetcsv ( int handle [, int length [, string delimiter [, string enclosure]]] )
handle
一個由 fopen()、popen() 或 fsockopen() 產生的有效檔案指針。
length （可選）
必須大於 CVS 檔案內最長的一行。在 PHP 5 中該參數是可選的。如果忽略（在 PHP 5.0.4 以後的版本中設為 0）該參數的話，那么長度就沒有限制，不過可能會影響執行效率。
delimiter （可選）
設定欄位分界符（只允許一個字元），默認值為逗號。
enclosure （可選）
設定欄位環繞符（只允許一個字元），默認值為雙引號。該參數是在 PHP 4.3.0 中添加的。
和 fgets() 類似，只除了 fgetcsv() 解析讀入的行並找出 CSV 格式的欄位然後返回一個包含這些欄位的數組。
fgetcsv() 出錯時返回 FALSE，包括碰到檔案結束時。
注意: CSV 檔案中的空行將被返回為一個包含有單個 null 欄位的數組，不會被當成錯誤。
例 1. 讀取並顯示 CSV 檔案的整個內容
$row = 1;
$handle = fopen("test.csv","r");
while ($data = fgetcsv($handle, 1000, ",")) {
$num = count($data);
echo "
$num fields in line $row:
\n";
$row++;
for ($c=0; $c < $num; $c++) {
echo $data[$c] . "
\n";
}
}
fclose($handle);

the enclosure param defaulting to " and giving a warning if it's an empty string makes this function nearly worthless. csv files do not always have the fields enclosed, and in those cases it doesn't work.
---------
I had the same problem with this as well, enclosure really should be possible to be made null.
However, perhaps a solution to the problem is to use "\n" as the enclosure character in fgetcsv. As far as I tested it seems to work out just fine. I was thinking of using "\0" but that may cause problems with some data files. If anyone knows of any issues that might crop up when using "\n" as enclosure, please post away. Thanks.

A 5.2 way to lazily parse a single CSV line
function parSECSV($str, $delimiter = ',', $enclosure = '"', $len = 4096)
{
$fh = fopen('php://memory', 'rw');
fwrite($fh, $str);
rewind($fh);
$result = fgetcsv( $fh, $len, $delimiter, $enclosure );
fclose($fh);
return $result;

Here is a simple to include the field names in the array. Altough this is very simple, it does the job fantastically
print_r(buildStock('stock.csv'));
function buildStock($File) {
$handle = fopen($File, "r");
$fields = fgetcsv($handle, 1000, ",");
while($data = fgetcsv($handle, 1000, ",")) {
$detail[] = $data;
}
$x = 0;
$y = 0;
foreach($detail as $i) {
foreach($fields as $z) {
$stock[$x][$z] = $i[$y];
$y++;
}
$y = 0;
$x++;
}
return $stock;

Thank you to the mystery contributor of csv_string_to_array function:
http://uk3.php.net/manual/en/function.fgetcsv.php#62524
This works great when your CSV data has literal commas inside enclosures that you want to preserve, fgetcsv fails at this & interprets comma as end of item even without ending enclosure.

If you had a problem with fgetcsv and multibyte characters, you have to set the correct local setting:
Setlocale(LC_ALL, 'en_US.UTF-8');
?>
Change it to your local settings and/or charset.

I find the documentation mildly misleading:
fgetcsv() does not - as this documentation seemingly claims in the descriptive line - get a line out of the file (via the file pointer) and then parses this for CSV fields, but instead retrieves a CSV row out of the file, which it then splits into an array.
The difference may seem trivial, but reading the description of this function I feared it might not support linebreaks in individual CSV values. Testing, however, revealed that fgetcsv() [fortunately!] works as one would expect from a CSV parser, and my fears were without cause.
In fact, fgetcsv() is remarkably hard to break. It's not confused by the value """,""" for example (three quotation marks followed by a comma followed by three quotation marks - which represents the value "quotation mark, comma, quotation mark" in case it's not immediately obvious).
I hope this extra documentation is helpful for someone.

I had a problem with fgetcsv and multibyte characters so i used one of functions below (16-Nov-2002 04:01 to be specific) and modified it to be (hopefully) multibyte safe.

$fields = array();
$fldCount = 0;
$inQuotes = false;
for ($i = 0; $i < mb_strlen($line); $i++) {
if (!isset($fields[$fldCount])) $fields[$fldCount] = "";
$tmp = mb_substr($line, $i, mb_strlen($delim));
if ($tmp === $delim && !$inQuotes) {
$fldCount++;
$i+= mb_strlen($delim) - 1;
}
else if ($fields[$fldCount] == "" && mb_substr($line, $i, 1) == '"' && !$inQuotes) {

Some time it is not very good to be dependent on system locale :( The hosting provider will not change locale for everyone. It is possible that correct locale is not installed at all. So there are lots of reimplementation of fgetscv ;)

Whenever you have to parse CSV data that isn't stored in a file, or should you need to encode your data as CSV, you may use my set of functions, featuring:
- bi-directional conversion, meaning you may read as well as write CSV data, to or from your arrays.
- Support for customizable field separator, newline character (also auto-detects and converts Win/Mac/*nix newlines).
- separators, newlines (auto-converted), properly handled within fields enclosed in quotation marks. Last line may or may not be terminated by a newline.
- checks for possibly corrupt data (whenever last field in last row starts, but is not terminated, with a quotation mark).
- Top speed guaranteed by use of strpos(), substr() etc.; room yet for some optimization (especially with associative arrays).
- Clean (no data stored or retrieved from outside function scope, except for CSVstruct array).
Requires PHP 4.3 or newer.
Enjoy!

If you need to import a huge CSV file into a database, use the bulk insert technique instead of many line-by-line inserts:
- MSSQL: bcp tool and "BULK INSERT" SQL
- MySQL: mysqlimport tool and "LOAD DATA INFILE" SQL
As for MySQL, you can use the ready "Quick CSV import" class at http://a4.users.phpclasses.org/browse/package/2917.html

Here is a OOP based importer similar to the one posted earlier. However, this is slightly more flexible in that you can import huge files without running out of memory, you just have to use a limit on the get() method
Sample usage for small files:-
-------------------------------------
$importer = new CsvImporter("small.txt",true);
$data = $importer->get();
print_r($data);
Sample usage for large files:-
-------------------------------------
$importer = new CsvImporter("large.txt",true);
while($data = $importer->get(2000))
{
print_r($data);
}
And heres the class:-
-------------------------------------
class CsvImporter
{
private $fp;
private $parse_header;
private $header;
private $delimiter;
private $length;
//--------------------------------------------------------------------
function __construct($file_name, $parse_header=false, $delimiter="\t", $length=8000)
{
$this->fp = fopen($file_name, "r");
$this->parse_header = $parse_header;
$this->delimiter = $delimiter;
$this->length = $length;
$this->lines = $lines;
if ($this->parse_header)
{
$this->header = fgetcsv($this->fp, $this->length, $this->delimiter);
}
}
//--------------------------------------------------------------------
function __destruct()
{
if ($this->fp)
{
fclose($this->fp);
}
}
//--------------------------------------------------------------------
function get($max_lines=0)
{
//if $max_lines is set to 0, then get all the data
$data = array();
if ($max_lines > 0)
$line_count = 0;
else
$line_count = -1; // so loop limit is ignored
while ($line_count < $max_lines && ($row = fgetcsv($this->fp, $this->length, $this->delimiter)) !== FALSE)
{
if ($this->parse_header)
{
foreach ($this->header as $i => $heading_i)
{
$row_new[$heading_i] = $row[$i];
}
$data[] = $row_new;
}
else
{
$data[] = $row;
}
if ($max_lines > 0)
$line_count++;
}
return $data;
}
//--------------------------------------------------------------------

Should you need it, here is a nice and simple function for escaping csv fields properly.
This version is conditional - it only adds quotes if needed:
function csv_escape($str) {
$str = str_replace(array('"', ',', "\n", "\r"), array('""', ',', "\n", "\r"), $str, &$count);
if($count) {
return '"' . $str . '"';
} else {
return $str;
}
}
?>
This version is even simpler, but adds quotes even if not needed.
function csv_escape($str) {
return = '"' . str_replace('"','""', $str) . '"';
}
?>

I modified the code for my own purposes, to return an array with named keys for each field. I tried various alternatives, and this seems to work well with exported Excel data.
ini_set("auto_detect_line_endings", 1);
$current_row = 1;
$handle = fopen("testdatasource.csv", "r");
while ( ($data = fgetcsv($handle, 10000, ",") ) !== FALSE )
{
$number_of_fields = count($data);
if ($current_row == 1)
{
//Header line
for ($c=0; $c < $number_of_fields; $c++)
{
$header_array[$c] = $data[$c];
}
}
else
{
//Data line
for ($c=0; $c < $number_of_fields; $c++)
{
$data_array[$header_array[$c]] = $data[$c];
}
print_r($data_array);
}
$current_row++;
}
fclose($handle);

Thank you donnoman and ramdac, that's exactly the kind of function I needed!
For my use, assigning metadata to images, I actually want the first dimension array key to be a string pulled from the CSV; the unique filename, instead of a number.
Easy, just insert the second dim's key...
Change: $return[]=$row;
To: $return[$data[0]]=$row;
(You may indeed wish to confirm unique values first!)
Also, if you find the fields getting out of sync, increase the $len byte count for the largest cell of data.

Note that fgetcsv() uses the system locale setting to make assumptions about character encoding.
So if you are trying to process a UTF-8 CSV file on an EUC-JP server (for example),
you will need to do something like this before you call fgetcsv():
setlocale(LC_ALL, 'ja_JP.UTF8');
[Also not that setlocale() doesn't *permanently* affect the system locale setting]

For those of you who need to get CSV data from a single line of quoted CSV (comma delimited) values (that may have commas in the data), use this:

$results=preg_split($expr,trim($str));
return preg_replace("/^\"(.*)\"$/","$1",$results);

$str=<<"testing, stuff, here","is testing ok",200,456
EOF;
print_r(csv_string_to_array($str));

I was using the function to import a csv file that had some values with "\" included this confused the import function to ignore the End of line and hence an incorrect number of rows is returned to me.
Suggest you try to replace that \ and { brackets as well since they have the same function of an escape character before u import the function
thanks
27-Feb-2006 11:05
beware of characters of binary value == 0, as they seem to make fgetcsv ignore the remaining part of a line where they appear.
Maybe this is normal under some convention I don't know, but a file exported from Excel had those as values for some cells *sometimes*, thus fgetcsv return variable cell counts for different lines.

a simple script to output the contents of a CSV file as a nice table - should be totally dynamic and can use any seperator - it does not have to be a comma (,).
I don't perclaim my code is 100% perfect or correct, but it works. useful if you back up your cell phone address book and it outputs CSV.
It works on the assumtion that the first line is the header row.
//Define what you want the seperator to be, this could be new line, (\n) a tab (\t) or any other char, for obvious reasons avoid using chars that will be present in the string. Id suggest a comma, or semicolon.
$sep = ",";
//define file to read
$file = "test.txt";
//read the file into an array
$lines = file($file);
//count the array
$numlines = count($lines);
//explode the first (0) line which will be the header line
$headers = explode($sep, $lines[0]);
//count the number of headers
$numheaders = count($headers);
$i = 0;
//start Formatting output
echo "
looping
| cells while($i<$numheaders){ $headers = str_replace("\"", "", $headers); echo " | ".$headers[$i]." | "; $i++; } echo "
| ".$fields[$x]." | "; $x++; } $y++; echo "

Based on my observations a few comments below I have written a class that incorporates all these features. Here is the class description:
----------
This class will parse a csv file in either standard or MS Excel format.
Two methods are provided to either process a line at a time or return the whole csv file as an array.
It can deal with:
- Line breaks within quoted fields
- Character seperator (usually a comma or semicolon) in quoted fields
- Can leave or remove leading and trailing spaces or tabs
- Can leave or skip empty rows.
- Windows and Unix line breaks dealt with automatically. (Care must be taken with Macintosh format.)
Also, the escape character is automatically removed.
-----------
So basically it should "just work". If it doesn't please send me an email ;-)
You can download it from: http://www.phpclasses.org/browse/package/2672.html
An example on how to use the class and a test.csv file are also provided.

Newer PHP versions handle cvs files slightly different than older versions.
"Max Mustermann"|"Muster Road 34b"|"Berlin" |"Germany"
"Sophie Master" |"Riverstreet" |"Washington"|"USA"
The extra spaces behind a few fields in the example (which are useful, when you manually manage a small csv database to align the columns) were ignored by fgetcsv from PHP 4.3. With the new 4.4.1 release they get appended to the string, so you end up with "Riverstreet " instead the expected "Riverstreet".
Easy workaround is to just trim all fields after reading them in.
while ( $data = fgetcsv($database, 32768, "|") )
{
$i = 0;
while(isset($data[$i]))
{
$data[$i] = rtrim($data[$i]);
$i++;
}
....
}

The fgetcsv function seems to follow the MS excel conventions, which means:
- The quoting character is escaped by itself and not the back slash.
(i.e.Let's use the double quote (") as the quoting character:
Two double quotes "" will give a single " once parsed, if they are inside a quoted field (otherwise neither of them will be removed).
\" will give \" whether it is in a quoted field or not (same for \\) , and
if a single double quote is inside a quoted field it will be removed. If it is not inside a quoted field it will stay).
- leading and trailing spaces (\s or \t) are never removed, regardless of whether they are in quoted fields or not.
- Line breaks within fields are dealt with correctly if they are in quoted fields. (So previous comments stating the opposite are wrong, unless they are using a different PHP version.... I am using 4.4.0.)
So fgetcsv if actually very complete and can deal with every possible situation. (It does need help for macintosh line breaks though, as mentioned in the help files.)
I wish I knew all this from the start. From my own benchmarks fgetcsv strikes a very good compromise between memory consumption and speed.
-------------------------
Note: If back slashes are used to escape quotes they can easily be removed afterwards. Same for leading and trailing spaces.

The man below suggested this to avoid and endless loop from using "!== FALSE":
while (($data = fgetcsv($handle, 1000, ",")) != FALSE) {
This is redundant, if you want to do it with the != you may as well do:
while ($data = fgetcsv($handle, 1000, ",")) {

Heres a function i wrote because all the other functions on here didnt work quiet as easy as I wanted them to:
It opens the CSV file, and reads it into a 3d array. If you set $columnsOnly, you will only get the first line.
function CSV2Array($OpenFile, $columnsOnly = false)
{
$handle = fopen ($openFile,"r");
$rows = 0;
while (!feof($handle)) {
$columns[] = explode(",", fgets($handle, 4096));
if ($rows++ == 0 && $columnsOnly)
break;
}
fclose ($handle);
return $columns;
}

"marc at henklein dot com" posted a cool function "CSV2Array", but there's an error. If the last char of the CSV file isn't a carriage return, the function can't take the last field of the last line in the CSV.
Fixed adding this check:
if ($content[strlen($content)-1]!="\r" && $content[strlen($content)-1]!="\n")
$content .= "\r\n";
?>
The updated function:
function CSV2Array($content, $delim = ';', $encl = '"', $optional = 1) {
if ($content[strlen($content)-1]!="\r" && $content[strlen($content)-1]!="\n")
$content .= "\r\n";
$reg = '/(('.$encl.')'.($optional?'?(?(2)':'(').
'[^'.$encl.']*'.$encl.'|[^'.$delim.'\r\n]*))('.$delim.
'|\r\n)/smi';
preg_match_all($reg, $content, $treffer);
$linecount = 0;
for ($i = 0; $i<=count($treffer[3]);$i++) {
$liste[$linecount][] = $treffer[1][$i];
if ($treffer[3][$i] != $delim)
$linecount++;
}
unset($linecount);
unset($i);
unset($reg);
unset($content);
unset($delim);
unset($encl);
unset($optional);

return $liste;

The file function reads the file in an array with the eol still attached, so the +1 is not necessary.
Bob Kolk

Dave Meiners above example is great, except that you need to need to add one to the final length to account for EOL. So it'd be:

Be wary of Example #1 above.
If the file doesn't exist, the application will spit out data to STDOUT and could fill up /tmp space if you're not careful. The output might will look like this:
PHP Warning: fgetcsv(): supplied argument is not a valid stream resource in...(your filename here)
To get around this, do the following:
row = 1;
if(!$handle = fopen("test.csv", "r"))
{
print 'could not open file. quitting';
die;
}
while (($data = fgetcsv($handle, 1000, ",")) !== FALSE) {
$num = count($data);
echo "
$num fields in line $row:

$row++;
for ($c=0; $c < $num; $c++) {

example 1 above goes into an infinte loop if the file name is bad because fgetcsv return a false result not identical to false but equl to false
to fix this use != instead of !== in the test as shown below it will still work correctly for the case when the file exists.
while (($data = fgetcsv($handle, 1000, ",")) != FALSE) {

In "php at dogpoop dot cjb dot net" post, I would change in his function:
function csv_split($line,$delim=",",$removeQuotes=true)
this code:
if ($line[$i+1] == '"') {
to:
if ($i+1 < strlen($line) && $line[$i+1] == '"') {
The reason is that if the quote (") is at the last line of the string, then it will try to reach an undefined space in the string, therefore giving a PHP error.
Of course his function is great if your line is a true compatible csv line, but I leave that to you to judge if you can do this assumption ;-)

I've had alot of projects recently dealing with csv files, so I created the following class to read a csv file and return an array of arrays with the column names as keys. The only requirement is that the 1st row contain the column headings.
I only wrote it today, so I'll probably expand on it in the near future.
class CSVparse
{
var $mappings = array();
function parse_file($filename)
{
$id = fopen($filename, "r"); //open the file
$data = fgetcsv($id, filesize($filename)); /*This will get us the */
/*main column names */
if(!$this->mappings)
$this->mappings = $data;
while($data = fgetcsv($id, filesize($filename)))
{
if($data[0])
{
foreach($data as $key => $value)
$converted_data[$this->mappings[$key]] = addslashes($value);
$table[] = $converted_data; /* put each line into */
} /* its own entry in */
} /* the $table array */
fclose($id); //close file
return $table;
}
}

The following modification will hide the unnecessary delimiter in the array
that is returned when fgetcsvfromline is called.
function fgetcsvfromline ($line, $columnCount, $delimiterChar = ',',
$enclosureChar = '"') {
global $regExpSpecialChars;
$matches = array();
$delimiterChar = strtr($delimiterChar, $regExpSpecialChars);
$enclosureChar = strtr($enclosureChar, $regExpSpecialChars);
$cutpoint = strlen($delimiterChar)+1;
$regExp = "/^";
for ($i = 0; $i < $columnCount; $i++) {
$regExp .= $enclosureChar.'?(.*?)'.$enclosureChar.'?'.$delimiterChar;
}
$regExp = substr($regExp,0,-$cutpoint).'/';
if (preg_match($regExp, $line, $matches)) {
return $matches;
}
return 0;
}
?>
=== If you were getting
[0] => "Ma"rk","Bergeron","rocks","12345,"times"
[1] => "
[2] => Ma"rk
[3] => "
..etc
You will now get
[0] => "Ma"rk","Bergeron","rocks","12345,"times"
[1] => Ma"rk

I found a way to parse CSVs with Perl RegExps and it's a lot faster and more efficient than the conventional fgetcsv() way.
The fgetcsv() took more than 2 minutes to parse a 15,000 lined file while my function takes 6 to 7 secs on a Celeron 366 MHz prehistoric machine.
Here's a link to the source of my function.

using the example above with a length of 1000 will truncate any csv rows longer than 1000 bytes, the remainder of that line will be represented next time you call $data = fgetcsv(). one solution i have seen to this is to use filesize("test.csv") as the length argument, however sometimes with large csv files you may encounter errors for exceeding the memory limit. to remedy this, i have read the csv file into an array, looping through that array to find the longest line in the csv, and then using that value as my length argument, unset($array) to free up the memory. im open to better solutions.
$length = 1000;
$array = file("test.csv");
for($i=0;$i {
if ($length < strlen($array[$i]))
{
$length = strlen($array[$i]);
}
}
unset($array);
$handle = fopen("test.csv", "r");
while ($data = fgetcsv($handle, $length, ","))
{
// do what you want with your array here.
}

For all those people struggling with Macintosh conversions, since PHP 4.3 there is a new runtime setting available:
auto_detect_line_endings boolean
When turned on, PHP will examine the data read by fgets() and file() to see if it is using Unix, MS-Dos or Macintosh line-ending conventions.
This enables PHP to interoperate with Macintosh systems, but defaults to Off, as there is a very small performance penalty when detecting the EOL conventions for the first line, and also because people using carriage-returns as item separators under Unix systems would experience non-backwards-compatible behaviour.

Here's one way to convert the data in a csv file to an html table:
$filename = "book1.csv"; //here's the filename
$id = fopen($filename, "r"); //open the file
while ($data = fgetcsv($id, filesize($filename))) //start a loop
$table[] = $data; //put each line into its own entry in the $table array
fclose($id); //close file
echo "
| $data | "; echo "
?>
You may need to change the parameters for fgetcsv() to suit your needs and probably change the table style.

I wrote this little thingy to allow the customer to upload csv-files to his page which will then automatically be converted to a php-include-file with a html-table for inclusion in his homepage.
Its a little buggy since it can't handle rowspan and such, but otherwise it works well.
function csv2php($filename, $delim=";",$path)
{
$row = 0;
$dump = array();
$once = 0;
$max_cols = 0;
// open file - get number of columns - make data Array
$f = fopen ($filename,"r");
$size = filesize($filename)+1;
while ($data = fgetcsv($f,$size,$delim,''))
{
for($o=0;$o {
if($once==0)
$max_cols++;
}
$dump[$row] = $data;
if($once==0)
$once=1;
$row++;
}
fclose ($f);
/////// make text for php-include file
$PrintText="
| "; if($dump[$x][$y]!="") $printtext.=$dump[$x][$y]; else $printtext.=" "; $printtext.=" | \n"; } $printtext.="
$ident = write_dammit($printtext,$path);
return $ident;
}
function write_dammit($printtext,$path)
{
$ident=time();
$filename=$ident;
$filename .= ".inc.php";
$filecontents = $printtext;
$fp = fopen("$path/$filename","w"); // if in windows you have to Chace the / to \\
fwrite($fp,$filecontents);
fclose($fp);
return $ident;
}
$ident = csv2php("table.csv",";","C:/your_include_folder/");
require($ident.".inc.php");

A little contribution to make it more easy to use this function when working with a database. I noticed this function doesn't add logical keys to the array, so I made a small function which creates a 2dimensional array with the corresponding keys added to the rows.
// this function requires that the first line of your CSV file consists of the keys corresponding to the values of the other lines
function convertCSVtoAssocMArray($file, $delimiter)
{
$result = Array();
$size = filesize($file) +1;
$file = fopen($file, 'r');
$keys = fgetcsv($file, $size, $delimiter);
while ($row = fgetcsv($file, $size, $delimiter))
{
for($i = 0; $i < count($row); $i++)
{
if(array_key_exists($i, $keys))
{
$row[$keys[$i]] = $row[$i];
}
}
$result[] = $row;
}
fclose($file);
return $result;
}

Important note about the CSV format:
There should *not* be any space in between the fields. For example,
field1, field2, field3 [Wrong!]
field1,field2,field3 [Correct-No space between fields]
If you add space between the fields, MS Excel won't recognize the fields (especially date and multi-line text fields).

I've seen alot of people talking about ways to convert from mac to unix or from dos to unix.
For DOS to UNIX I use dos2unix in the "tofrodos Ver 1.4" package.
http://www.thefreecountry.com/tofrodos/index.shtml
For Mac to UNIX I have the follwing in my .bashrc
alias mac2unix="perl -pi -e 'tr/\015/\012/'"
Just run dos2unix or mac2unix and it will convert. My life has been easier ever since I started installing these utilities.

beware of using this function in two different php versions,
in php 4.3 the 4th parameter can be given altough empty
in php 4.2 you get just a warning but it is not able to read the csv file if you place an enclosure that is empty

If anyone else is taking on the task of converting from Filemaker Pro to MySQL, you might find this useful:
Here's a collection of simple functions that take a CSV file, re-formats the data and writes to a file with MySQL INSERTs.
ORIGINAL DATA:
"1", "foo", "2"
"3", "bar", "4"
OUTPUT
INSERT info mysql_table VALUES('', '1', 'foo', '2');
INSERT info mysql_table VALUES('', '3', 'bar', '4');
For simple data it works alright, but I could not find a way to escape the contents before assembling the INSERT statements - kept getting "bad argument for implode()"...
/*************************************
* main *
*************************************/
$file = "path/to/your/file.txt";
$tbl = "your_MySQL_table";
$CSVarray = get_csv($file);
$CSVarray = makeINSERTS($CSVarray, "$tbl");
$filetowrite = $_POST["file"]."_sql.txt";
$fp = fopen($filetowrite, "w");
while (list($key, $val) = @each($CSVarray)) {
fwrite($fp, $val);
}
fclose($fp);
chmod($filetowrite, 0777);
echo "File written Successfully";
}

You should pay attention to the fact that "fgetcsv" does remove leading TAB-chars "chr(9)" while reading the file.
This means if you have a chr(9) as the first char in the file and you use fgetcsv this char is automaticaly deleted.
Example:
file content:
chr(9)first#second#third#fourth
source:
$line = fgetcsv($handle,500,"#");
The array $line looks like:
$line[0] = first
$line[1] = second
$line[2] = third
$line[3] = fourth
and not
$line[0] = chr(9)first
$line[1] = second
$line[2] = third
$line[3] = fourth
All chr(9) after another char is not deleted!
Example:
file content:
Achr(9)first#second#third#fourth
source:
$line = fgetcsv($handle,500,"#");
The array $line looks like:
$line[0] = Achr(9)first
$line[1] = second
$line[2] = third
$line[3] = fourth

For those of you having problems with Excel's version of CSV file exports (which include the infamous ^M characters in *NIX editors, such as VIM) here is a simple script to remove them and replace them in the normal UNIX newline character (\n).
$fp = fopen('/dev/stdin','r');
while(!feof($fp)){
$line = chop(fgets($fp,4096));
$ret = ereg_replace(chr(13) . chr(10),"\n",$line);
$ret = ereg_replace(chr(13),"\n",$ret);
echo $ret."\n";
}
fclose($fp);
?>
Usage: cat file_with_windows_newlines | php -q strip_newlines.php > outfile
(this works for other stuff too, like PHP "coders" who use Notepad and upload to a UNIX environment).

Quick and dirty script to take a csv file and turn it into a multidimensional associative array structure using the first line of the csv as the hash key names.
$i = 0;
$handle = fopen ("file.csv","r");
while($data = fgetcsv ($handle, 1000, ",")) {
if ($i == 0) { $key_arr = $data; }
reset($key_arr);
while(list($index,$name) = each($key_arr)) { $temp_arr[$name] = $data[$index]; }
$result_arr[$i] = $temp_arr;
$i++;
}
fclose ($handle);

This is the solution to Microsoft Excel csv file - this function add last delimiter in line.
function delimiter()
{
if (is_file("file.csv"))
{
$fp = fopen($file.csv,"r");
while (false!=($line = fgets($fp)))
{
$line = "$line;";
putf($line);
}
fclose($fp);
}
}
//puts dedlimited line in new file
function putf($line)
{
$fp = fopen($file,"a");
fputs($fp,$line);
fclose($fp);
}
/* this readsl line at the time and adds ; as delimiter on line end. Its easy and helpfull*/
delimiter();

Here's piece of code I wrote that reads the first line of a CSV file, creates an array based the field's name, and then reads the rest of the contents of the CSV file into the approate arrays. Great for quick and dirty access to a CSV file.
// Name of the file to read/
// $openFile is the only varible you will have change to for this to work.
$openFile = "test.csv";
$row = 0;
$handle = fopen ($openFile,"r");
while ($data = fgetcsv ($handle, 1000, ",")) {
if($row == 0){
// set the varible array
$num = count ($data);
$csvNames = array();
for ($c=0; $c < $num; $c++) {
$csvNames[$c] = $data[$c];
eval("$" . $data[$c] . " = array();");
}
$row = 1;
}else{
$num = count ($data);
$row++;
for ($c=0; $c < $num; $c++) {
$buildEval = "$" . $csvNames[$c] . "[" . ($row - 1) . "] = \"" . $data[$c] . "\";";
eval($buildEval );
}
}
}
fclose ($handle);

fgetcsv stops reading your file?
I had to write a script to validate and import a large amount of data to MySQL and it would stop running. I've noticed, after trawling the internet for a solution, quite a few people have had similar problems.
Solution? Like a dope I had forgotten to put in
set_time_limit()
within a loop. Otherwise the script would time out before it finished importing all the data.
Moral of the story? Only suppress errors after your script works with a large amount of test data!

This function takes a csv line and splits it into an array, much like fgetcsv does but you can use it on data that isn't coming in from a file, or you can read data from a file some other way (like if your Mac files aren't being read correctly) and use this to split it. If you have any corrections, comments (good or bad), etc. I would appreciate an email to the above address.
function csv_split($line,$delim=",",$removeQuotes=true) {
#$line: the csv line to be split
#$delim: the delimiter to split by
#$removeQuotes: if this is false, the quotation marks won't be removed from the fields
$fields = array();
$fldCount = 0;
$inQuotes = false;
for ($i = 0; $i < strlen($line); $i++) {
if (!isset($fields[$fldCount])) $fields[$fldCount] = "";
$tmp = substr($line,$i,strlen($delim));
if ($tmp === $delim && !$inQuotes) {
$fldCount++;
$i += strlen($delim)-1;
} else if ($fields[$fldCount] == "" && $line[$i] == '"' && !$inQuotes) {
if (!$removeQuotes) $fields[$fldCount] .= $line[$i];
$inQuotes = true;
} else if ($line[$i] == '"') {
if ($line[$i+1] == '"') {
$i++;
$fields[$fldCount] .= $line[$i];
} else {
if (!$removeQuotes) $fields[$fldCount] .= $line[$i];
$inQuotes = false;
}
} else {
$fields[$fldCount] .= $line[$i];
}
}
return $fields;

If you're working in Excel on a Mac and are exporting a spreadsheet as a CSV, PHP won't recognise the line breaks, and interprets the file as one really long line. It borders on a bug really. For me, I just open the file in BBEdit or BBEdit Lite, convert the file from Mac to Unix, and all is well. But if you're dealing with user-contributed files, you'll need to convert the line-endings first... replacing all \r's with \n's should do it.

Quoting csv is pretty simple, and there are two steps..I note in previous comments only the second step has been explained.
First fields with double quotes need to double up the quotes, ie _He said "Timmy"..._ should become _He said ""Timmy""..._
secondly as mentioned above, fields with commas need double quotes.
Here is a simple function to achieve this, that I pass to array walk, if you want to use it somewhere else, prob get rid of reference and return the value.
function check_csv_field_ref(&$item) {
$item = str_replace('"', '""', $item);
if (strpos($item, ",") !== FALSE) {
$item = '"' . $item . '"';
}
