|
||
|
|
|
||
|
|
```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();
|
||
|
|
|
||
|
|
$Bool = $MadelineProto->channels->checkUsername(['channel' => InputChannel, 'username' => 'string', ]);
