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();

$messages.AffectedHistory = $MadelineProto->channels->deleteUserHistory(['channel' => InputChannel, 'user_id' => InputUser, ]);

messages.AffectedHistory = channels.deleteUserHistory({channel=InputChannel, user_id=InputUser, })
