PHP Fatal error: Using $this when not in object context

Question

I\'ve got a problem:

I\'m writing a new WebApp without a Framework.

In my index.php I\'m using: require_once(\'load.php\');

Answer 1

When you call the function in a static context, $this simply doesn't exist.

You would have to use this::xyz() instead.

To find out what context you're in when a function can be called both statically and in an object instance, a good approach is outlined in this question: How to tell whether I’m static or an object?
