Re: PHP compared to JSP

Caching is not going against PHP as long as whenever the file is changed of the 1st access it would be cached, rather then caching php scripts based on some arbitrary timer. Ideally the caching script would on the 1st access of the script convert the script to binary code which can then be executed right away without needing to pass through an interpreter. Just like you would run a compiled C program. I suspect such caching solution would greatly boost the speed of any PHP page. Unfortunately, as far as I know no current PHP caching solution does this.

It's not PHP's place to do this. Currently, it would be Zend's place to do this, as they have somewhat of a monopoly on the PHP engine. Obviously not a "monopoly" like, well, MS, but there's not any notable support or demand for alternative PHP engines. Current caches cache the zend 'opcodes' (as far as I can tell), and the Zend engine translates to machine code during execution. If anything was to do this, that's the place where it would/should happen. I'd read about someone planning a PHP -> C compiler, but haven't seen anything on it yet. This might alleviate speed problems for people (although it would introduce a longer write/compile/test cycle). Michael Kimsal http://www.logicreate.com/ 734-480-9961
