更新日志

版本	说明
8.0.0	`shmop` expects a Shmop instance now; previously, a resource was expected.

shmop_close doesn't delete the memory segment, it just detaches from it.


If you have created the block and need to delete it you must call shmop_delete **BEFORE** calling shmop_close (for reasons outlined in shmop_delete help page notes).

As explained on this page, PHP 8.0.0 expects a Shmop instance instead of a resource. According to bug #81098 this change 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 change in 8.0.0 expects the expected argument changed without mentioning it'll just throw a deprecation error.
