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). Defaults as a comma: ,.
The optional enclosure parameter sets the field enclosure (one character only) and defaults to a double quotation mark: ".
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.
