Parse error after deploy Laravel 5.1 on shared hosting

I am using Laravel 5.1

To get rid of Public folder:

1. I moved everything in a folder named 'root' except public folder.

2. Move all public folder content in Root.

3. Changed require __DIR__.'/root/bootstrap/autoload.php'; & $app = require_once __DIR__.'/root/bootstrap/app.php'; in index.php at root folder.

Everything is working perfectly in localhost. I uploaded my project in a shared hosting. And change database information in .env and change the url in Config\App.php 'url' => 'localhost', to 'url' => 'http://ift.tt/1jdbkqA',.

Now when I go to myproject.com it shows a Parse error Parse error: syntax error, unexpected 'class' (T_CLASS), expecting identifier (T_STRING) or variable (T_VARIABLE) or '{' or '$' in /home/zamzamtransport/public_html/index.php on line 50

index.php:

require __DIR__.'/root/bootstrap/autoload.php';

$app = require_once __DIR__.'/root/bootstrap/app.php';

$kernel = $app->make(Illuminate\Contracts\Http\Kernel::class);
$response = $kernel->handle(
    $request = Illuminate\Http\Request::capture()
);

$response->send();

$kernel->terminate($request, $response);

Another problem is my .env file is accessible.
