### MadelineProto Example ([now async for huge speed and parallelism!](https://docs.madelineproto.xyz/docs/ASYNC.html)):
|
|
|
|
|
|
```php
|
|
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, 'peer' => InputPeer, 'start_param' => 'string', ]);
