PHP setlocale / strftime output differs between cli and web

Question

I know there are many questions about locale issues in PHP. But I can't find any similar question or answer. I need to output German month names on a website. German locale is installed. Here is the output of locale -a:

# locale -a
C
C.UTF-8
POSIX
de_DE
de_DE.iso88591
de_DE.iso885915@euro
de_DE.utf8
de_DE@euro
deutsch
en_US.utf8
german

Now I just use a little test snippet:

<?php
echo setlocale(LC_ALL, 'de_DE.utf8')."\n";
echo strftime('%B %Y', strtotime('2022-03-20'))."\n";

Here is the correct output from executing it on the command line:

# php test.php
de_DE.utf8
März 2022

Now when I execute the same snippet on the same server with a web browser (file:///x.php) the correct locale will be loaded, but the output is in English:

de_DE.utf8
March 2022

Apache 2.4.38 is used as the web server. The php cli version is 7.2.34 and the php module on apache is php7_module (shared). There must be a difference between the php cli and php apache modules, but I don't know the solution?

Thanks for help!

From another question: try setting multiple names. Perhaps cli and module use different names for the same locale? — Michel

Thanks, yes i tried also de_DE, de_DE.UTF-8, de_DE.iso88591. Always the same problem? — Gunnar Gläser

I found the solution. The problem was solved after disabling the Perl module with a2dismod perl. After this the website shows also the correct date format.

Difference between executing PHP code from the commandline and from the HTTP side. Check the difference for this: php_ini_loaded_file

Thanks for your hint. I just compared the cli and apache php.ini version and I don't find a difference that causes this problem.
