Wann werden shared memory Blöcke tatsächlich gelöscht, abgesehen vom Herunterfahren von Apache?

Shared memory blocks are typically deleted when the Apache server is shut down. However, if you want to delete them manually without restarting Apache, you can use the `shm_remove()` function in PHP to explicitly remove the shared memory block. 

<?php
$shm_key = ftok(__FILE__, 't');
$shm_id = shmop_open($shm_key, 'c', 0644, 100); // Open or create a shared memory block
// Do something with the shared memory block
shmop_close($shm_id); // Close the shared memory block
shmop_delete($shm_id); // Delete the shared memory block
?>
