Good in-depth technical documentation on PHP

Question

Possible Duplicate:
where can i learn php internals, how they work?

Are there any good resources for really in depth technical details on php, i.e. the nuts a bolts of how it works.

Most resources don't go beyond actually how to use the language. Im interested in finding out what goes on below it all (from a high level perspective i.e. i dont want to sit a read the c code :) )

this might help : http://www.youtube.com/watch?v=bxxIXPc9IR8 — tereško, May 30 '12 at 18:52
@BenBarden I didn't downvote but one could consider this question not-useful because of the dupe. — Mike B, May 30 '12 at 18:57

I would start with the internals section of the PHP Manual.

There's also an internals page in the PHP Wiki.
