Though it says **shm_identifier** in
int shm_remove(int shm_identifier);
and
shm_attach() returns an **id** that that can be used to access the System V...
a snippet like this:
<?php
$key = 1234;
$shm=shm_attach($key);
// do whatever...
shm_remove($shm);
?>
produces an error like
Warning: 2(which is the value of $shm) is not a existing SysV shared memory key in
/usr/cu/web/sema.php on line 44...
The documentation confused me a bit. I thought shm_remove would get the shm handle/id that returns
from shm_attach, not the key given to shm_attach. So, use instead:
shm_remove($key);
which is what is intended indeed.
