Even if you have no intention of becoming a PHP core developer or creating a PECL extension, cursory knowledge of PHP's inner workings can prove useful. This session will examine the lifecycle of a PHP request and equip you with essential knowledge and tools that can be used to diagnose the occasional segfault or language bug, decipher what a poorly documented SPL class actually does, and confidently answer why a PHP or C implementation is most warranted for a given problem.

Good look into how the internals work! I learned a good bit about when interacting with strace and generating backtraces and interacting with them with gdb.
Nice overview and a nicely balanced view at the topic.
