MadelineProto Example (now async for huge speed and parallelism!):

if (!file_exists('madeline.php')) {
    copy('https://phar.madelineproto.xyz/madeline.php', 'madeline.php');
}
include 'madeline.php';

$MadelineProto = new \danog\MadelineProto\API('session.madeline');
$MadelineProto->start();

$X = $MadelineProto->invokeWithLayer(['layer' => int, 'query' => !X, ]);

Or, if you're into Lua:

X = invokeWithLayer({layer=int, query=!X, })
