Getting process memory used

[minsu]

$pid = getmypid();

this returns process ID for my PHP script - how do i determine whats the memory taken by this apache process ?

since we run into chrooted environment ps wont work

I must find this from PHP script (the goal is to have some logic within shutdown function that will check if process uses more than specified memory - it should be terminated)

let me know

There are a couple user notes in the manual at "memory_get_usage" that might help.
