This article shows a code example of 6 ways that PHP sends a GET, POST request, using File_get_contents, fopen, Fsockopen, and curl to send get and post requests, with the following code: Method 1: Use file_get_contents to get the content in the Get mode:
1 <? PHP 2     $url= ' http://www.jb51.net/'; 3     $html file_get_contents ($url); 4     Echo $html ; 5 ?>
Method 2: Open the URL with fopen and get the content in get:
 1  <? php  2   $fp  =  ( $url , ' R '  3  stream_get_meta_data ($FP);  4  5   $result. = Fgets ($fp, 1024x768);  6   7  echo "url body: $result";  8  fclose ($FP);  9 ? 
Method 3: Use the file_get_contents function to get the URL by post
1<?PHP2     $data=Array(' foo ' = ' bar ');3     $data=Http_build_query($data);4  5     $opts=Array (6' HTTP '= = Array (7' Method ' = ' POST ',8' Header ' = ' content-type:application/x-www-form-urlencodedrn '. "Content-length:".strlen($data) . "RN",Ten' Content '= $data One         ) A     ); -   -     $context = stream_context_create ($opts); the$html = file_get_contents (' http://localhost/e/admin/test.html ',false,$context); -   -     Echo $html; -?>
Method 4: Open the URL with the Fsockopen function, get the complete data in Get mode, including header and Body,fsockopen need php.ini allow_url_fopen option to open
1<?PHP2     functionGet_url ($url,$cookie=false)3     {4$url=Parse_url($url);5         $query=$url[path]. "?".$url[query];6         Echo"Query:".$query;7         $fp=Fsockopen($url[Host],$url[Port]?$url[Port]:80,$errno,$errstr, 30);8         if(!$fp) {9             return false;Ten}Else { One             $request= "GET$queryHttp/1.1rn "; A             $request. = "Host:$url[Host]rn]; -             $request. = "Connection:Closern "; -             if($cookie)$request. = "Cookie:$cookien"; the $request.="RN"; -             fwrite($fp,$request); -              while([email protected]feof($fp)) { -                 $result.= @fgets($fp, 1024); +             } -             fclose($fp); +             return $result; A         } at     } -     //gets the HTML part of the URL, removing the header -     functionGeturlhtml ($url,$cookie=false) -     { -         $rowdata= Get_url ($url,$cookie); -         if($rowdata) in         { -             $body=Stristr($rowdata,"Rnrn"); to             $body=substr($body, 4,strlen($body)); +             return $body; -} the   *         return false; $     }Panax Notoginseng?>
Method 5: Use the Fsockopen function to open the URL, post to get the full data, including header and body
1<?PHP2     functionHttp_post ($URL,$data,$cookie,$referrer= "")3     {4  5         //parsing the given URL6         $URL _info=parse_url ($URL);7  8         //Building referrer9If$referrer= = "")//if not given use this script as referrerTen             $referrer= "111″; One   A         //making string from $data -         foreach($data  as $key=$value) -             $values[]=]$key= ".UrlEncode($value); the         $data _string=implode("&",$values); -   -         //Find out which port was needed–if not given use standard (=80) -if(!isset($URL _info["Port"])) +             $URL _info["Port"]=80; -   +         //Building Post-request: A         $request. = "POST".$URL _info["Path"]. " Http/1.1n "; at         $request. = "Host:".$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 "; -   in         $request. = "Cookie:$cookien"; -   to         $request.="n"; +         $request.=$data _string."n"; -   the         $fp=Fsockopen($URL _info["Host"],$URL _info["Port"]); *         fputs($fp,$request); $          while(!feof($fp)) {Panax Notoginseng              $result.=fgets($fp, 1024); -         } the         fclose($fp); +   A         return $result; the     } +?>
Method 6: Using the Curl Library, before using the Curl Library, you may need to see if php.ini has the curl extension turned on
1<?PHP2     $ch=curl_init ();3    $timeout= 5;4curl_setopt ($ch, Curlopt_url, ' http://www.jb51.net/');5curl_setopt ($ch, Curlopt_returntransfer, 1);6curl_setopt ($ch, Curlopt_connecttimeout,$timeout);7     $file _contents= Curl_exec ($ch);8Curl_close ($ch);9  Ten     Echo $file _contents; One?>
