PHP Installation & Error Message Display in Linux

I am learning PHP. I know it may not be top choice for many but somehow, I kind of like it. I made couple of videos and uploaded it in YouTube. One is how to install PHP 8.1 into Debian Linux Server and other one is how to configure PHP so that you can see the error messages in your browser. Some of you who are working with PHP as newbies like myself, may find these two videos useful in some extent.

Here are the hotspot links:
PHP Installation in Debian Linux : PHP 8.1 Installation with Apache2 - YouTube
PHP Error Message Configuration in Debian Linux : PHP Error Configuration - YouTube

Thanks for watching my tutorials.
