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 = $MadelineProto->messages->startBot(['bot' => InputUser, 'chat_id' => InputPeer, 'start_param' => 'string', ]);

Updates = messages.startBot({bot=InputUser, chat_id=InputPeer, start_param='string', })
