用法

GET用法：

$curl = new Curl();
$curl->get(‘http://www.111cn.net/’);

POST用法

$curl = new Curl();
$curl->get(‘http://www.111cn.net/’, ‘p=1&time=0′);

function getrealurl($url){
 $header = get_headers($url,1);
 if (strpos($header[0],'301') || strpos($header[0],'302')) {
  if(is_array($header['Location'])) {
   return $header['Location'][count($header

['Location'])-1];
  }else{
   return $header['Location'];
  }
 }else {
  return $url;
 }
}

$url = 'http://111cn.net';

print_r(get_headers($url));
