get_headers — 取得服务器响应一个 HTTP 请求所发送的所有标头
array get_headers ( string $url [, int $format ] )
如果地址有效则返回一个数组,否则返回false,当第二个参数为1时,会解析相应的信息并设定数组的键名,返回关联数组
eg:
<?php $url = 'http://www.investfree-brk.com'; print_r(get_headers($url)); print_r(get_headers($url, 1)); ?>
以上结果输出如下:
Array(
[0] => HTTP/1.1 200 OK
[1] => Date: Sat, 29 May 2004 12:28:13 GMT
[2] => Server: Apache/1.3.27 (Unix) (Red-Hat/Linux)
[3] => Last-Modified: Wed, 08 Jan 2003 23:11:55 GMT
[4] => ETag: "3f80f-1b6-3e1cb03b"
[5] => Accept-Ranges: bytes
[6] => Content-Length: 438
[7] => Connection: close
[8] => Content-Type: text/html
