FR: Compatibilize with supported PHP version

[narcisgarcia]

Trying Chamilo in a Debian GNU/Linux 12 (Stable) server, just following the Install Chamilo link I get a page with message:

Deprecated: mb_convert_encoding(): Handling HTML entities via mbstring is deprecated; use htmlspecialchars, htmlentities, or mb_encode_numericentity/mb_decode_numericentity instead in /srv/www/somtecnologia.com/www/site.tree/public/lms/chamilo/main/inc/lib/internationalization.lib.php on line 1210

Although I read on Chamilo project website "Chamilo only supports PHP 7.4", I'm asking to developer team to compatibilize it with PHP versions 8.1 to 8.4 , the only currently supported and included in major OS distributions and servers.

Related issue: #5849

Note that Debian GNU/Linux 11 (Old) provided PHP 7.3 and not 7.4 version exactly.

Web UI installation wizard says in green text:
Your PHP version matches the minimum requirement: 8.2.26

But I see "A test course has been created successfully: NO" and New Installation button is disabled and I can't follow process.
This test course course item is the only one I see in red color value.

SORRY; this is another subject: bug #2373

I believe the vast majority of issues with PHP 8.3 have been solved. I wouldn't go into 8.4, but at least it runs on 8.3 and I just spent 20 minutes crazy-clicking and filling forms and cannot find anything weird, so I'm closing this one.
