What folder with php to specify if there is no /usr/local/bin/php folder?

Question

xampp

In the atom settings, they ask you to specify the path to the folder with php, or to php itself, but how can I understand which one I need to specify if I have a huge number of them?

Plus, when I want to see the version of a package in xammp, ubuntu just doesn't see them, is it possible to point to the php path for xdebug to work in atom using xammp?

Command "mysql" not found but can be installed with:
sudo apt install mysql-client-core-8.0 # version 8.0.17-0ubuntu2, or
sudo apt install mariadb-client -core-10.3 # version 1:10.3.17-1
[email protected]:~$ php -v
"php" command not found but can be installed with:
sudo apt install php7.3-cli

xammp itself works

I have a lot of problems installing the lamp, so I decided to install xammp
