class Request{
    public static function post($url, $post_data = ‘‘, $timeout = 5){//curl
        $ch = curl_init();
        curl_setopt ($ch, CURLOPT_URL, $url);
        curl_setopt ($ch, CURLOPT_POST, 1);
        if($post_data != ‘‘){
            curl_setopt($ch, CURLOPT_POSTFIELDS, $post_data);
        }
        curl_setopt ($ch, CURLOPT_RETURNTRANSFER, 1); 
        curl_setopt ($ch, CURLOPT_CONNECTTIMEOUT, $timeout);
        curl_setopt($ch, CURLOPT_HEADER, false);
        $file_contents = curl_exec($ch);
        curl_close($ch);
        return $file_contents;
    }

    public static function post2($url, $data){//file_get_content    
        $postdata = http_build_query(
            $data
        );
        $opts = array(‘http‘ =>
                      array(
                          ‘method‘  => ‘POST‘,
                          ‘header‘  => ‘Content-type: application/x-www-form-urlencoded‘,
                          ‘content‘ => $postdata
                      )
        );
        $context = stream_context_create($opts);
	$result = file_get_contents($url, false, $context);
        return $result;
    }

    public static function post3($host,$path,$query,$others=‘‘){//fsocket        
　　　　$post="POST $path HTTP/1.1\r\nHost: $host\r\n";        
　　　　$post.="Content-type: application/x-www-form-";        
　　　　$post.="urlencoded\r\n${others}";        
　　　　$post.="User-Agent: Mozilla 4.0\r\nContent-length: ";        
　　　　$post.=strlen($query)."\r\nConnection: close\r\n\r\n$query";        
　　　　$h=fsockopen($host,80);        
　　　　fwrite($h,$post);        
　　　　for($a=0,$r=‘‘;!$a;){                
　　　　　　$b=fread($h,8192);                
　　　　　　$r.=$b;                
　　　　　　$a=(($b==‘‘)?1:0);            
　　　　}        
　　　　fclose($h);        
　　　　return $r;    
　　}
}

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/1.1\n";
    $request.="Host: ".$URL_Info["host"]."\n";
    $request.="Referer: $referer\n";
    $request.="Content-type: application/x-www-form-urlencoded\n";
    $request.="Content-length: ".strlen($data_string)."\n";
    $request.="Connection: close\n";
        $request.="Cookie:   $cookie\n";
        $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;
    }
    ?>
