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.
