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_ChannelDifference = $MadelineProto->updates->getChannelDifference(['channel' => InputChannel, 'filter' => ChannelMessagesFilter, 'pts' => int, 'limit' => int, ]);

Or, if you're into Lua:

updates_ChannelDifference = updates.getChannelDifference({channel=InputChannel, filter=ChannelMessagesFilter, pts=int, limit=int, })
