It rather depends what for and where you're using it.

Assuming its for generating web pages, called as CGI, fast CGI or module,
then don't worry - the runtime memory gets blown away after servicing each
request.

IME PHP does a very good job of tracking what memory it has allocated - I've
run servers fielding millions of hits per day and only had to take them
down for patching.
