I'm on ElementaryOS (basically Ubuntu) and have PHP 8.2 installed. I'm trying to get the mbstring extension. When I install it, it says I already have it:
$ sudo apt-get install php8.2-mbstring
Reading package lists... Done
Building dependency tree... Done
Reading state information... Done
php8.2-mbstring is already the newest version (8.2.12-1+ubuntu22.04.1+deb.sury.org+1).
The following packages were automatically installed and are no longer required:
javascript-common libc-ares2 libjs-highlight.js libnode72 nodejs-doc
Use 'sudo apt autoremove' to remove them.
0 upgraded, 0 newly installed, 0 to remove and 435 not upgraded.
However, phpinfo said that it's disabled:
Multibyte decoding support using mbstring disabled
And I was receiving errors on my website related to not having this extension.
I uncommented ;extension=mbstring in the php.ini file and now it says that it's enabled. However, starting the Laravel dev server emits this warning:
$ php artisan serve
PHP Warning: Module "mbstring" is already loaded in Unknown on line 0
WARN PHP Warning: Module "mbstring" is already loaded in Unknown on line 0.
INFO Server running on [http://127.0.0.1:8000].
Press Ctrl+C to stop the server
What does this warning mean and is there a way to get rid of it but still use mbstring?
