PHP

Description

fputcsv(
 resource $stream,
 array $fields,
 string $separator = ",",
 string $enclosure = "\"",
 string $escape = "\\",
 string $eol = "\n"
): int|false

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

Parameters

stream: 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.
separator: The optional separator parameter sets the field delimiter (one single-byte character only).
enclosure: The optional enclosure parameter sets the field enclosure (one single-byte character only).
escape: The optional escape parameter sets the escape character (at most one single-byte character). An empty string ("") disables the proprietary escape mechanism.
eol: The optional eol parameter sets a custom End of Line sequence.

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.

Return Values

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

Changelog

Version	Description
8.1.0	The optional `eol` parameter has been added.
7.4.0	The `escape` parameter now also accepts an empty string to disable the proprietary escape mechanism.

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.
