说明

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

Writes the fields array to the file as a CSV line.

参数

fields

An array of values.

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.

注意:

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

返回值

Returns the length of the written string 或者在失败时返回 false.

Returns false, and does not write the CSV line to the file, if the separator or enclosure parameter is not a single character.

错误/异常

An E_WARNING level error is issued if the separator or enclosure parameter is not a single character.

更新日志

版本 说明
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.

范例

示例 #1 SplFileObject::fputcsv() example

<?php

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

$file = new SplFileObject('file.csv''w');

foreach (
$list as $fields) {
    
$file->fputcsv($fields);
}

?>

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

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

This method is available in PHP 5.4 and it is just a wrapper over php.net/fputcsv.
