benchmarking used memory

Hi, I would like to know if there is way to measure how much memory a script uses during execution. Althought threre is no such function in the manual, in my opinion there must be some indication how much memory is used because of the memory_limit directive in the php.ini file. So if php is able to determine the maximum level it should be able and to give indication and for the actual.
