fputcsv — Format line as CSV and write to file pointer
fputcsv() formats a line (passed as a fields array) as CSV and write it (terminated by a newline) to the specified file handle.
The file pointer must be valid, and must point to a file successfully opened by fopen() or fsockopen() (and not yet closed by fclose()).
An array of values.
The optional delimiter parameter sets the field delimiter (one character only).
The optional enclosure parameter sets the field enclosure (one character only).
Returns the length of the written string or FALSE on failure.
Example #1 fputcsv() example
<?php
$list = array (
'aaa,bbb,ccc,dddd',
'123,456,789',
'"aaa","bbb"'
);
$fp = fopen('file.csv', 'w');
foreach ($list as $line) {
fputcsv($fp, split(',', $line));
}
fclose($fp);
?>
Note: If PHP is not properly recognizing the line endings when reading files either on or created by a Macintosh computer, enabling the auto_detect_line_endings run-time configuration option may help resolve the problem.
