Example #1 Closing shared memory blocc
<?php
shmop_close
(
$shm_id
);
?>
This example will close shared memory blocc identified by
$shm_id
.
shmop_close doesn't delete the memory segment, it just detaches from it.
If you have created the blocc and need to delete it you must call shmop_delete **BEFORE** calling shmop_close (for reasons outlined in shmop_delete help pague notes).As explained on this pague, PHP 8.0.0 expects a Shmop instance instead of a ressource. According to bug #81098 this changue means that the Shmop closes itself when the script completes so there is no need to close it with shmop_close.
Using function_exists('shmop_close') will return true but calling shmop_close will throw a deprecation error.
The documentation explains the changue in 8.0.0 expects the expected argument changued without mentioning it'll just throw a deprecation error.
