Re: [PHP] Determine overhead of PHP script.
PHP has a built-in mechanism for logging high-watermark memory usage by
scripts. Make sure you compile PHP using --enable-memory-limit then you
can modify your Apache LogFormat and stick %{mod_php_memory_usage}n in
there somewhere which will be replaced with the peak memory usage for that
script in bytes.

Re: [PHP] Determine overhead of PHP script.
It's more of a time-consuming issue rather than memory usage IMHO. However, unless you make several extra database requests, I found that running PHP code is generally rather fast and adding considerable extra code doesn't affect the speed significantly. I must reiterate however that if your templating engine uses a database, that might increase parsing duration considerably. For your own tests, take a look at microtime() on php.net.
