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();

$updates.Difference = $MadelineProto->updates->getDifference(['pts' => int, 'pts_total_limit' => int, 'date' => int, 'qts' => int, ]);

Or, if you're into Lua:

updates.Difference = updates.getDifference({pts=int, pts_total_limit=int, date=int, qts=int, })
