Error when hosting site, which does not appreciate when testo in localhost

I'm trying to upload a website that I made using cakephp 3.5.10. The site is working normally on my PC, the problem is when I try to put it online in the hostgator, which gives this error:

Parse error: syntax error, unexpected T_STRING, expecting T_CONSTANT_ENCAPSED_STRING or '(' in /home/jessica059/public_html/site.net.br/areadocliente/webroot/index.php on line 33

// Check platform requirements

if (php_sapi_name() === 'cli-server') {
    $_SERVER['PHP_SELF'] = '/' . basename(__FILE__);

    $url = parse_url(urldecode($_SERVER['REQUEST_URI']));
    $file = __DIR__ . $url['path'];
    if (strpos($url['path'], '..') === false && strpos($url['path'], '.') !== false && is_file($file)) {
        return false;
    }
}
require dirname(__DIR__) . '/vendor/autoload.php';

use App\Application;
use Cake\Http\Server;

// Bind your application to the server.
$server = new Server(new Application(dirname(__DIR__) . '/config'));

// Run the request/response through the application and emit the response.
$server->emit($server->run());

I took a look at Hostgator's CPanel and the version of php that was la era 3.2 so I changed it to 3.6, updated the page of the site and still the error continues.

I'm completely lost as it's my first time putting up a website online.
