‘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 $html;方法4：用fsockopen函数打开url，以get方式获取完整的数据，包括header和body,fsockopen需要 PHP.ini 中 allow_url_fopen 选项开启function get_url ($url,$cookie=false)$url = parse_url($url);$query = $url[path].” ”.$url[query];echo “Query:”.$query;$fp = fsockopen( $url[host], $url[port] $url[port]:80 , $errno, $errstr, 30);if (!$fp) {return false;} else {$request = “GET $query HTTP/1.1rn”;$request .= “Host: $url[host]rn”;$request .= “Connection: Closern”;if($cookie) $request.=”Cookie: $cookien”;$request.=”rn”;fwrite($fp,$request);while(!@feof($fp)) {$result .= @fgets($fp, 1024);fclose($fp);return $result;//获取url的html部分，去掉headerfunction GetUrlHTML($url,$cookie=false)$rowdata = get_url($url,$cookie);if($rowdata)$body= stristr($rowdata,”rnrn”);$body=substr($body,4,strlen($body));return $body;return false; 方法5：用fsockopen函数打开url，以POST方式获取完整的数据，包括header和bodyfunction HTTP_Post($URL,$data,$cookie, $referrer=”")// parsing the given URL$URL_Info=parse_url($URL);// Building referrerif($referrer==”") // if not given use this script as referrer$referrer=”111″;// making string from $dataforeach($data as $key= $value)$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
$ch = curl_init();$timeout = 5;curl_setopt ($ch, CURLOPT_URL, ‘http://www.phpstudy.net/');curl_setopt ($ch, CURLOPT_RETURNTRANSFER, 1);curl_setopt ($ch, CURLOPT_CONNECTTIMEOUT, $timeout);$file_contents = curl_exec($ch);curl_close($ch);echo $file_contents; PHP教程
