Install PHP 7 on Ubuntu 20.04

If you have a server, you probably want to install PHP.
A while ago I thought PHP is really primitive (I only used Java/JSP) but WordPress has changed that forever.

Install PHP and PHP MySQL library (you will probably need it)

sudo apt install php libapache2-mod-php php-mysql

Install additional PHP libraries (whatever you need)

sudo apt install php-pear php-curl php-dev php-gd php-mbstring php-zip php-xml

(you may add other extensions now, or install what you need later)

That’s it.
