方法1: 用file_get_contents 以get方式获取内容：

方法2: 用fopen打开url, 以get方式获取内容：

方法3：用file_get_contents函数,以post方式获取url
‘bar');$data = http_build_query($data);$opts = array (‘http' => array (‘method' => ‘post',‘header'=> “content-type: application/x-www-form-urlencodedrn” .“content-length: ” . strlen($data) . “rn”,‘content' => $data));$context = stream_context_create($opts);$html = file_get_contents(‘http://localhost/e/admin/test.html', false, $context);echo $html;?>
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
$value)$values[]=”$key=”.urlencode($value);$data_string=implode(“&”,$values);// find out which port is needed – if not given use standard (=80)if(!isset($url_info[port]))$url_info[port]=80;// building post-request:$request.=”post “.$url_info[path].” http/1.1n”;$request.=”host: “.$url_info[host].”n”;$request.=”referer: $referern”;$request.=”content-type: application/x-www-form-urlencodedn”;$request.=”content-length: “.strlen($data_string).”n”;$request.=”connection: closen”;$request.=”cookie: $cookien”;$request.=”n”;$request.=$data_string.”n”;$fp = fsockopen($url_info[host],$url_info[port]);fputs($fp, $request);while(!feof($fp)) {$result .= fgets($fp, 1024);}fclose($fp);return $result;}?>
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
