# fputcsv

(PHP 5)

fputcsv -- Format line as CSV and write to file pointer

## Description

int fputcsv ( resource handle [, array fields [, string delimiter [, string enclosure]]] )

fputcsv() formats a line (passed as a fields array) as CSV and write it to the specified file handle. Returns the length of the written string, or `FALSE` on failure.

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: ".

例子 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); ?>`

> 注: 如果碰到 PHP 在读取文件时不能识别 Macintosh 文件的行结束符，可以激活 auto_detect_line_endings 的运行时配置选项。
