php模拟post提交数据的方法

function A_bbslogin($user_login,$password,$host,$port="80"){
//需要提交的post数据
$argv = array(
cookie => array(user_login =>$user_login, password => $password,_wp_http_referer=>/bbpress/,re=>,remember=>true)

$params[] = $key . = . $value;

$header .= "Content-Length: " . strlen($params) . "\r\n";
$header .= "Connection: Close\r\n\r\n";
$header .= $params;
$fp = fsockopen($host, $port);
fputs($fp, $header);
while(!feof($fp)) {
$str = fgets($fp); //以下是自己的逻辑代码,这里主要是模拟cookie,可用来同步登陆
if(!(strpos($str,"Set-Cookie:") === false)){
