phpVolcano has a pointer to a new article (the second in a series) about some of the internals behind the Zend Engine in PHP.

Trickie has released a new article on the PHP internals that he is presenting for the Melbourne PHP user group tonight. There is not much real code yet ( that is comming in the next installment ), but he does a good job going through some of the base internal things.

The first part, in case you missed it.

For anyone out in the Melbourne area, I'd recommend that you stop on into the meeting (details), and check out this series. It hasn't gotten too heavily into the code, but it does give a good overview of what you can expect poking around in the PHP internals...
