方法3：用file_get_contents函数,以post方式获取url

 1  'bar');   3  4 //生成url-encode后的请求字符串，将数组转换为字符串   5 $data = http_build_query($data);   6 $opts = array (   7   'http' => array (   8       'method' => 'POST',   9       'header'=> "Content-type: application/x-www-form-urlencoded\r\n" .  10       "Content-Length: " . strlen($data) . "\r\n",  11       'content' => $data  12   )  13 );  14 //生成请求的句柄文件  15 $context = stream_context_create($opts);  16 $html = file_get_contents('http://localhost/e/admin/test.html', false, $context);  17 echo $html;  18 ?>  

方法4：用fsockopen函数打开url，以get方式获取完整的数据，包括header和body,fsockopen需要 PHP.ini 中 allow_url_fopen 选项开启

方法5：用fsockopen函数打开url，以POST方式获取完整的数据，包括header和body

 1 $value)  11 $values[]="$key=".urlencode($value);  12 $data_string=implode("&",$values);  13     // Find out which port is needed - if not given use standard (=80)  14 if(!isset($URL_Info["port"]))  15 $URL_Info["port"]=80;  16     // building POST-request:  17 $request.="POST ".$URL_Info["path"]." HTTP/1.1\n";  18 $request.="Host: ".$URL_Info["host"]."\n";  19 $request.="Referer: $referer\n";  20 $request.="Content-type: application/x-www-form-urlencoded\n";  21 $request.="Content-length: ".strlen($data_string)."\n";  22 $request.="Connection: close\n";  23     $request.="Cookie:   $cookie\n";  24     $request.="\n";  25 $request.=$data_string."\n";  26     $fp = fsockopen($URL_Info["host"],$URL_Info["port"]);  27 fputs($fp, $request);  28 while(!feof($fp)) {  29 $result .= fgets($fp, 1024);  30 }  31 fclose($fp);  32     return $result;  33 }  34 ?>  35 36 37  

方法6:使用curl库，使用curl库之前，可能需要查看一下php.ini是否已经打开了curl扩展
