如何利用PHP发送GET请求

方法一：用fopen()打开url

<?php  $fp = fopen($url, ‘r');  stream_get_meta_data($fp);  while(!feof($fp))  {   $result .= fgets($fp, 1024);    }  echo “url body: $result”;  fclose($fp);  ?>

方法二：用file_get_contents()

<?php      $url='https://www.adminn.cn/';      $html = file_get_contents($url);     echo $html;  ?>

方法三：用fsockopen()函数打开url，fsockopen()函数需要 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;   }  ?>
