Description:
------------
In PHP 8.0.6, shmop_close returns me a Deprecated error, but the function_exists method returns me true. I don't know if it's an error in the shmop method, or the function_exists method.

configure line:
./configure --enable-mbstring --with-mysqli --enable-shmop --enable-pcntl

Test script:
---------------
<?php
echo var_export(function_exists("shmop_close"), true);
if (function_exists("shmop_close")) shmop_close();

Expected result:
----------------
false

Actual result:
--------------
true
Deprecated: Function shmop_close() is deprecated in [...]

function_exists returns whether the function exists. Deprecated functions still exist.

as the function exists but is deprecated why in the world should it return anything else but true? 

if it wouldn't exist you would get a fatal error 

that's what deprecations all about: warning about stuff which will be removed in the future so that you notice it and fix your code before it's removed in later releases

Ok it's true. My fault. Thanks for support :)

Can I ask here why is shmop_close marked as deprecated? I didn't see anything in the docs.
Can I submit an issue in the doc-en repo?

Since PHP 8.0, the shmop functions use objects instead of resources, thus there is no need to call shmop_close (PHP will do that automatically when the object is no longer used).

This is not currently documented.

The documentation has been updated in the meantime.
