Hi there andylonger,

Just on a quick scan of your code, this seems to be the cause of your error, php is assuming a constant, because you haven't put '' around the array element this usually references a constant doing that.

$depth[parser]++; needs to be: $depth['parser']++;

If the element was being reference by a variable, this would be what it looks like: $depth[$parser] but I don't know whether or not that is what your needing to use or whether your after the element name...

There may be other little things, but for now that's all I can see.

Cheers,
