fputcsv

(PHP 5 >= 5.1.0, PHP 7)

fputcsv — Format line as CSV and write to file pointer

Description

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

fputcsv() formats a line (passed as a fields array) as CSV and writes 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 strings.
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 (at most one character). An empty string ("") disables the proprietary escape mechanism.

Note:

If an enclosure character is contained in a field, it will be escaped by doubling it, unless it is immediately preceded by an escape_char.

Return Values

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

Changelog

Version	Description
7.4.0	The `escape_char` parameter now also accepts an empty string to disable the proprietary escape mechanism.
5.5.4	The `escape_char` parameter was added

Examples

Example #1 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"""

Notes

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.
