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();

$Document = $MadelineProto->messages->getDocumentByHash(['sha256' => 'bytes', 'size' => int, 'mime_type' => 'string', ]);

Or, if you're into Lua:

Document = messages.getDocumentByHash({sha256='bytes', size=int, mime_type='string', })
