get_headers:发送服务器响应HTTP请求
get_headers(字符串url[链接格式])
get_headers()以数组的形式返回服务器HTTP请求。如果执行失败,将返回FALSE和一个错误的水平E_WARNING》。
可选参数设置为1,get_headers()能分析系统的响应速度和集数组中的键。

注意
:使用该函数需要把 php.ini里面的allow_url_fopen = On,才能使用。

实例如下
$url = http://www.ite5e.com;
print_r(get_headers($url));
print_r(get_headers($url, 1));
?>

打印结果

[0] => HTTP/1.1 200 OK
[1] => Connection: close
[2] => Date: Tue, 16 Nov 2010 09:48:20 GMT
