seriously - why should it be unavailable suddenly on Fedora 33 after 15 years?

[root@rawhide ~]# php -r "echo (int)function_exists('posix_initgroups');"
1

[root@rawhide ~]# php -v

btw In case you're interested in investigating why that is unavailable on your system, that define is setup from here I believe: https://github.com/php/php-src/blob/65c789148b72e62d22fb23abaa1e0c97ba74c6da/ext/posix/config.m4#L13

Hi, 

The availability of that function depends on the detection of whether 'INITGROUPS' (whatever that is) is available for that system:

https://github.com/php/php-src/blob/65c789148b72e62d22fb23abaa1e0c97ba74c6da/ext/posix/posix.c#L1176

So this is probably a doc bug.

Also, please take the effort to make your reproduce cases be short http://sscce.org/

If you paste walls of text, it reduces the chances of people being able to see what the problem is.

Sorry, but your problem does not imply a bug in PHP itself.  For a
list of more appropriate places to ask for help using PHP, please
visit http://www.php.net/support.php as this bug system is not the
appropriate forum for asking support questions.  Due to the volume
of reports we can not explain in detail here why your report is not
a bug.  The support channels will be able to provide an explanation
for you.

Thank you for your interest in PHP.

what about simply load the posix extension in your config?
