Well maybe you should try and see what in your script is taking up lots of
memory.

They are very clue full. A program which uses X MB of memory is very likely
to use X MB of memory again at a later time. For example, how does it help
you if your 14 MB were shrunk back to 10 MB on each request. The next
request would probably make it grow back to 14 MB.
There might be some memory management libraries that shrink the memory back
but I doubt you can gain much from it especially as memory fragmentation
can severally limit the amount of memory you can reclaim and because of the
point I made before, it's probably just not worth it.
If you can find a case where you really think PHP is using much too much
memory let me know and we can try and check together if there's a way to
improve the situation.
