Just a quick note from over on Sterling Hughes' weblog this morning about his talk given on "PHP Inside/Out".

In this PDF file, you can see the listing of the entire presentation, and get more detail on what your PHP is really doing when you call it remotely. It's almost a combination of a beginner's HOWTO on PHP and a simple look at how some of the core works, and how you can benefit from it. Sterling and Thies also bring up a few good points near the end - like the possible need for a multipass compiler (to make the code even more efficient), or the optimizing of allocation of memory and the like.

Many thanks to Harry Fuecks for pointing this one out...
