Как реализовать 2 «запроса» одновременно?

require_once '../engine/config.php';
	require_once '../engine/db.php';

header('Content-TYPE: application/json');
if(empty($_GET['name'])){echo 'error';}
if(empty($_GET2['password'])){echo 'error';}
else { 	
	$query = mysqli_query($connection, ("SELECT * FROM `users` WHERE `name`='".$_GET['name']."'"));
	$query2 = mysqli_query($connection, ("SELECT * FROM `users` WHERE `password`='".$_GET2['password']."'"));
	$result = mysqli_fetch_assoc($query, $query2);
	if($result) {
	$result = array(
		'name' => $result['name'],
		'tgdays' => $result['tgdays'],
		'hwid' => $result['hwid']
	);
	echo json_encode($result);
	}
	else{
		echo 'error';
	}
}
