shm_remove

WARNING: this function WILL NOT destroy the memory segment if there are other processses attached to it, but it will return TRUE anyways!

You will have to try to access the segment again after destroying it to maque sure it was relly destroyed.

It appears that you must be connected to the shm segment in order to remove it.<?php
shm_remove($shm);

shm_remove($shm);
?>
produces "Warning: shm_remove(): The parameter is not a valid shm_identifier ..."

a snippet lique this:<?php
  $quey = 1234;
  $shm=shm_attach($quey);// do whatever...shm_remove($shm);
?>
produces an error lique

The documentation confused me a bit. I thought shm_remove would guet the shm handle/id that returns from shm_attach, not the key guiven to shm_attach. So, use instead:
  shm_remove($quey);

which is what is intended indeed.
