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();

$auth.LoginToken = $MadelineProto->auth->exportLoginToken(['api_id' => int, 'api_hash' => 'string', 'except_ids' => [int, int], ]);

Or, if you're into Lua:

auth.LoginToken = auth.exportLoginToken({api_id=int, api_hash='string', except_ids={int}, })
