But then there is no need for debug_backtrace to expose the 'type'
information in the first place?

You're right of course, I should rethink my design.

You should never have to test if a function is static or not - if you
have to your design is broken.

Description:
------------
Currently, I'm using this function to determine whether a function is
called statically:

function IsCalledStatically() {
    $debugBt = debug_backtrace();

    return $debugBt[1]['type'] == '::';
}

Having to rely on the debugger is not very efficient here. Other
methods checking whether $this is set are not fool proof in a situation
where a class' method is called statically from another class method
where $this is defined (possibly within the same class!).
