Question

I’m using querystring with $_REQUEST array and each time I want to access an any key I use this condition

if(array_key_exists('scene_id', $_REQUEST))

Is there any way to directly use $_REQUEST["scene_id"] without any warnings and errors?

You could wrap that in your own function ofcourse:

function request($key, $default=null) {
    return isset($_REQUEST[$key])
        ? $_REQUEST[$key]
        : $default;
}

echo request('scene_id');
