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' => $password,'_wp_http_referer'=>'/bbpress/','re'=>'','remember'=>true)
);
foreach($argv['cookie'] as $key => $value) {
$params[] = $key . '=' . $value;
}
$params = implode('&', $params);
$header = "POST /bbpress/bb-login.php HTTP/1.1\r\n";
$header .= "Host:$host:$port\r\n";
$header .= "Content-Type: application/x--form-urlencoded\r\n";
$header .= "Content-Length: " . strlen($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)){
$tmparray = explode(" ",$str);
$cookiearray = explode("=",$tmparray[1]);
$cookiepaths = explode("=",$tmparray[6]);
$cookiename = urldecode($cookiearray[0]);
$cookievalue = urldecode(substr($cookiearray[1],0,strlen($cookiearray[1])-1));
$cookietime = time()+3600247;
$cookiepath = urldecode(substr($cookiepaths[1],0,strlen($cookiepaths[1])-1));
setcookie($cookiename,$cookievalue,$cookietime,$cookiepath);
}
}
fclose($fp);
}
