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函數打開url，以POST方式擷取完整的資料，包括header和body

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;

}

?>
