方法 1: 用 file_get_contents 以 get 方式获取内容:
- <?php
- $url='http://www.51growup.com/';
- $html = file_get_contents($url);
- echo $html;
- ?>
方法 2: 用 fopen 打开 url, 以 get 方式获取内容:
- <?php
- $fp = fopen($url, 'r');
- stream_get_meta_data($fp);
- while(!feof($fp)) {
- $result .= fgets($fp, 1024);
- }
- echo "url body: $result";
- fclose($fp);
- ?>
方法 3: 用 file_get_contents 函数, 以 post 方式获取 url
- <?php
- $data = array ('foo' => '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://www.51growup.com/e/admin/test.html', false, $context);
- echo $html;
- ?>
方法 4: 用 fsockopen 函数打开 url, 以 get 方式获取完整的数据, 包括 header 和 body,fsockopen 需要 PHP.ini 中 allow_url_fopen 选项开启
- <?php
- function get_url ($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 $result;
- }
- }
- // 获取 url 的 html 部分, 去掉 header
- function GetUrlHTML($url,$cookie=false)
- {
- $rowdata = get_url($url,$cookie);
- if($rowdata)
- {
- $body= stristr($rowdata,"rnrn");
- $body=substr($body,4,strlen($body));
- return $body;
- }
- return false;
- }
- ?>
方法 5: 用 fsockopen 函数打开 url, 以 POST 方式获取完整的数据, 包括 header 和 body
- <?php
- function HTTP_Post($URL,$data,$cookie, $referrer="")
- {
- // parsing the given URL
- $URL_Info=parse_url($URL);
- // Building referrer
- if($referrer=="") // if not given use this script as referrer
- $referrer="111";
- // making string from $data
- foreach($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
- <?php
- $ch = curl_init();
- $timeout = 5;
- curl_setopt ($ch, CURLOPT_URL, 'http://www.51growup.com/');
- curl_setopt ($ch, CURLOPT_RETURNTRANSFER, 1);
- curl_setopt ($ch, CURLOPT_CONNECTTIMEOUT, $timeout);
- $file_contents = curl_exec($ch);
- curl_close($ch);
- echo $file_contents;
- ?>
