php获取远程文件头

无意中发现的，说不定以后可以用到。 

程序:
/**
 * @name test.php
 * @date Sun Jan 19 18:59:31 CST 2008
 * @copyright 马永占(MyZ)
 * @author 马永占(MyZ)
 * @link http://blog.csdn.net/mayongzhan/
 */
$url = 'http://127.0.0.1/';
print_r(get_headers($url));
print_r(get_headers($url, 1));
?>
 
结果:
Array
(
    [0] => HTTP/1.1 200 OK
    [1] => Date: Sat, 19 Jan 2008 11:08:13 GMT
    [2] => Server: Apache/2.2.4 (Win32) PHP/5.2.3 DAV/2
    [3] => Content-Length: 1025
    [4] => Connection: close
    [5] => Content-Type: text/html;charset=utf-8
)
