I found that the fputcsv examples for PHP 4 missed one thing, that was proper handling of the $enclosure value when it is a quote (if a quote is passed in a field, and it is delimited by a slash, it will be improperly handled by the functions submitted here).
My modified function was built using the actual PHP5 source for fputcsv, with the addition of properly reacting to the existence of a delimited quote in the field being processed.
<?php
if (!function_exists('fputcsv')) {
function fputcsv(&$handle, $fields = array(), $delimiter = ',', $enclosure = '"') {
// Sanity Check
if (!is_resource($handle)) {
trigger_error('fputcsv() expects parameter 1 to be resource, ' .
gettype($handle) . ' given', E_USER_WARNING);
return false;
}
if ($delimiter!=NULL) {
if( strlen($delimiter) < 1 ) {
trigger_error('delimiter must be a character', E_USER_WARNING);
return false;
}elseif( strlen($delimiter) > 1 ) {
trigger_error('delimiter must be a single character', E_USER_NOTICE);
}
/* use first character from string */
$delimiter = $delimiter[0];
}
if( $enclosure!=NULL ) {
if( strlen($enclosure) < 1 ) {
trigger_error('enclosure must be a character', E_USER_WARNING);
return false;
}elseif( strlen($enclosure) > 1 ) {
trigger_error('enclosure must be a single character', E_USER_NOTICE);
}
/* use first character from string */
$enclosure = $enclosure[0];
}
$i = 0;
$csvline = '';
$escape_char = '\\';
$field_cnt = count($fields);
$enc_is_quote = in_array($enclosure, array('"',"'"));
reset($fields);
foreach( $fields AS $field ) {
/* enclose a field that contains a delimiter, an enclosure character, or a newline */
if( is_string($field) && (
strpos($field, $delimiter)!==false ||
strpos($field, $enclosure)!==false ||
strpos($field, $escape_char)!==false ||
strpos($field, "\n")!==false ||
strpos($field, "\r")!==false ||
strpos($field, "\t")!==false ||
strpos($field, ' ')!==false ) ) {
$field_len = strlen($field);
$escaped = 0;
$csvline .= $enclosure;
for( $ch = 0; $ch < $field_len; $ch++ ) {
if( $field[$ch] == $escape_char && $field[$ch+1] == $enclosure && $enc_is_quote ) {
continue;
}elseif( $field[$ch] == $escape_char ) {
$escaped = 1;
}elseif( !$escaped && $field[$ch] == $enclosure ) {
$csvline .= $enclosure;
}else{
$escaped = 0;
}
$csvline .= $field[$ch];
}
$csvline .= $enclosure;
} else {
$csvline .= $field;
}
if( $i++ != $field_cnt ) {
$csvline .= $delimiter;
}
}
$csvline .= "\n";
return fwrite($handle, $csvline);
}
}
?>

When I use the function above to write my data into a csv file, it will write all in one column. Actually I want to write in several columns like:
A B C C
1 2 3 4
How to to this? And how to output a specified cells? Like I want to start write from line 9, and column B.

I converted this from the PHP source code. This replicates PHP5 functionality exactly, whereas the other examples here do not.
<?php
if (!function_exists('fputcsv')) {
function fputcsv(&$handle, $fields = array(), $delimiter = ',', $enclosure = '"') {
$str = '';
$escape_char = '\\';
foreach ($fields as $value) {
if (strpos($value, $delimiter) !== false ||
strpos($value, $enclosure) !== false ||
strpos($value, "\n") !== false ||
strpos($value, "\r") !== false ||
strpos($value, "\t") !== false ||
strpos($value, ' ') !== false) {
$str2 = $enclosure;
$escaped = 0;
$len = strlen($value);
for ($i=0;$i<$len;$i++) {
if ($value[$i] == $escape_char) {
$escaped = 1;
} else if (!$escaped && $value[$i] == $enclosure) {
$str2 .= $enclosure;
} else {
$escaped = 0;
}
$str2 .= $value[$i];
}
$str2 .= $enclosure;
$str .= $str2.$delimiter;
} else {
$str .= $value.$delimiter;
}
}
$str = substr($str,0,-1);
$str .= "\n";
return fwrite($handle, $str);
}
}
?>

A event simpler way:
function fputcsv($hFile, $aRow, $sSeparator=',', $sEnclosure='"')
{
foreach ($aRow as $iIdx=>$sCell)
$aRow[$iIdx] = str_replace($sEnclosure, $sEnclosure.$sEnclosure, $sCell);
fwrite($hFile, join($aRow, $sSeparator)."\n");
}

This function is a replacement for PHP 4. It basically takes an array you pass it, and creates a delimited string. If you want ot use the key as the field name, you can tell the second paramater to use the key. The last is the delimiter you want each value to be seperated by. Should be pretty straight forward.
<?php
function generate_csv_data($data,$use_key=false,$delm=',') {
$output = NULL;
if(is_array($data)) {
if($use_key == false) {
if(isset($data[0]) && is_array($data[0])) {
foreach($data as $key) {
$output .= implode($delm,$key);
$output .= "\n";
}
} else {
$output .= implode("$delm", $data)."\n";
}
} else {
foreach($data as $key => $value) {
$output .= "$key{$delm}$value\n";
}
}
} else {
$output = $data;
}
if(empty($output)) {
trigger_error('OUTPUT WAS EMPTY!', E_USER_ERROR);
return false;
}
return $output;
}
?>

Compact fputcsv function(), for Php version >= 4.0.5 and < 5.1.
Not a "good programming practice", but if you need save bytes ...
function fputcsv($fp, $arr, $del=",", $enc="\"") {
fwrite($fp, (count($arr)) ? $enc . implode("{$enc}{$del}{$enc}", str_replace("\"", "\"\"", $arr)) . $enc . "\n" : "\n");
}

If you need to save the output to a variable (e.g. for use within a framework) you can write to a temporary memory-wrapper and retrieve it's contents:
<?php
// output up to 5MB is kept in memory, if it becomes bigger it will automatically be written to a temporary file
$csv = fopen('php://temp/maxmemory:'. (5*1024*1024), 'r+');
fputcsv($csv, array('blah','blah'));
rewind($csv);
// put it all in a variable
$output = stream_get_contents($csv);
?>

If you need to send a CSV file directly to the browser, without writing in an external file, you can open the output and use fputcsv on it..
<?php
$out = fopen('php://output', 'w');
fputcsv($out, array('this','is some', 'csv "stuff", you know.'));
fclose($out);
?>

Here is an adaptation to boonerunner's function for fputcsv.
It uses a 2-dimensional array.
Each sub-array is a line in the csv file which then ends up being seperated by commas.
function fputcsv($filePointer,$dataArray,$delimiter=",",$enclosure="\""){
// Write a line to a file
// $filePointer = the file resource to write to
// $dataArray = the data to write out
// $delimeter = the field separator
// Build the string
$string = "";
// for each array element, which represents a line in the csv file...
foreach($dataArray as $line){
// No leading delimiter
$writeDelimiter = FALSE;
foreach($line as $dataElement){
// Replaces a double quote with two double quotes
$dataElement=str_replace("\"", "\"\"", $dataElement);
// Adds a delimiter before each field (except the first)
if($writeDelimiter) $string .= $delimiter;
// Encloses each field with $enclosure and adds it to the string
$string .= $enclosure . $dataElement . $enclosure;
// Delimiters are used every time except the first.
$writeDelimiter = TRUE;
}
// Append new line
$string .= "\n";
} // end foreach($dataArray as $line)
// Write the string to the file
fwrite($filePointer,$string);
}

Here is an adaption of the above code that adds support for double quotes inside a field. (One double quote is replaced with a pair of double quotes per the CSV format).
<?php
function fputcsv($filePointer,$dataArray,$delimiter,$enclosure)
{
// Write a line to a file
// $filePointer = the file resource to write to
// $dataArray = the data to write out
// $delimeter = the field separator
// Build the string
$string = "";
// No leading delimiter
$writeDelimiter = FALSE;
foreach($dataArray as $dataElement)
{
// Replaces a double quote with two double quotes
$dataElement=str_replace("\"", "\"\"", $dataElement);
// Adds a delimiter before each field (except the first)
if($writeDelimiter) $string .= $delimiter;
// Encloses each field with $enclosure and adds it to the string
$string .= $enclosure . $dataElement . $enclosure;
// Delimiters are used every time except the first.
$writeDelimiter = TRUE;
} // end foreach($dataArray as $dataElement)
// Append new line
$string .= "\n";
// Write the string to the file
fwrite($filePointer,$string);
}
?>

What about cells that span multiple lines? This function allows for cells to contain newlines:
function fputcsv($handle, $row, $fd=',', $quot='"')
{
$str='';
foreach ($row as $cell)
{
$cell = str_replace($quot, $quot.$quot, $cell);
if (strchr($cell, $fd) !== FALSE || strchr($cell, $quot) !== FALSE || strchr($cell, "\n") !== FALSE)
{
$str .= $quot.$cell.$quot.$fd;
}
else
{
$str .= $cell.$fd;
}
}
fputs($handle, substr($str, 0, -1)."\n");
return strlen($str);
}
I found this reference on the web:

I found the following problems with the below function:
- when calling str_replace(), you must assign $cell the return value or nothing gets saved
- when using strchr(), you should explicitly check !== FALSE, or it'll treat a return value of 0 (found the character at string position 0) as FALSE
- Excel seems to quote not only fields containing commas, but fields containing quotes as well, so I've added another strchr() for quotes; I'm not saying Microsoft knows the correct way for sure, but it seems reasonable to me
- the original function put a space after each comma; that might be legal, I don't know, but I've never seen it (and I don't think it is, because then how would you indicate you wanted a field to start with a space other than by quoting it?)
- the original function didn't correctly return the length of the data outputted
Here's the function, fixed up a bit:
function fputcsv($handle, $row, $fd=',', $quot='"')
{
$str='';
foreach ($row as $cell) {
$cell=str_replace(Array($quot, "\n"),
Array($quot.$quot, ''),
$cell);
if (strchr($cell, $fd)!==FALSE || strchr($cell, $quot)!==FALSE) {
$str.=$quot.$cell.$quot.$fd;
} else {
$str.=$cell.$fd;
}
}
fputs($handle, substr($str, 0, -1)."\n");
return strlen($str);
}

The function in the prior comment doesn't escape quotes in fields, here mine:
function fputcsv($handle, $row, $fd=',', $quot='"')
{
$str='';
foreach ($row as $cell) {
str_replace(Array($quot, "\n"),
Array($quot.$quot, ''),
$cell);
if (strchr($cell, $fd)) {
$str.=$quot.$cell.$quot.$fd.' ';
} else {
$str.=$cell.$fd.' ';
}
}
fputs($handle, substr($str, 0, -2)."\n");
return $str-1;
}

Here's a simplistic fputcsv function that you can use until the real one gets out of CVS:
function fputcsv($filePointer, $dataArray, $delimiter, $enclosure){
// Write a line to a file
// $filePointer = the file resource to write to
// $dataArray = the data to write out
// $delimeter = the field separator
// Build the string
$string = "";
$writeDelimiter = FALSE;
foreach($dataArray as $dataElement){
if($writeDelimiter) $string .= $delimiter;
$string .= $enclosure . $dataElement . $enclosure;
$writeDelimiter = TRUE;
} // end foreach($dataArray as $dataElement)
// Append new line
$string .= "\n";
// Write the string to the file
fwrite($filePointer, $string);
} // end function fputcsv($filePointer, $dataArray, $delimiter)
