fputcsv

(PHP 5 >= 5.1.0, PHP 7)

Format line as CSV and write to file pointer

int fputcsv ( resource $handle, array $fields [, string $delimiter = "," [, string $enclosure = '"' [, string $escape_char = "\" ]]] )

fputcsv() formats a line (passed as a fields array) as CSV and write it (terminated by a newline) to the specified file handle.

Parameters:

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()).

fields

An array of values.

delimiter

The optional delimiter parameter sets the field delimiter (one character only).

enclosure

The optional enclosure parameter sets the field enclosure (one character only).

escape_char

The optional escape_char parameter sets the escape character (one character only).

Returns:

Returns the length of the written string or FALSE on failure.

Changelog:

5.5.4

The escape_char parameter was added

Notes:

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.

Examples:

fputcsv() example

<?php

$list = array (
    array('aaa', 'bbb', 'ccc', 'dddd'),
    array('123', '456', '789'),
    array('"aaa"', '"bbb"')
);

$fp = fopen('file.csv', 'w');

foreach ($list as $fields) {
    fputcsv($fp, $fields);
}

fclose($fp);
?>

The above example will write the following to file.csv:

aaa,bbb,ccc,dddd
123,456,789
"""aaa""","""bbb"""
