| php模拟post提交数据,用处很多,可用来网站的采集,登陆等等 //以程序登陆一个论坛登录为例function 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 .
