This guide assumes you have already successfully installed LAMPP.

Step 1 – install symfony

sudo wget https://get.symfony.com/cli/installer -O - | bash

Step 2 – move the installed files to make the installation global on your system:

mv /home/[your home folder]/.symfony/bin/symfony /usr/local/bin/symfony

Step 3 – check if it works. Enter:

symfony

Step 4 – Check if your system meets all requirements. Type:

symfony check:requirements

Step 5 – If you have a fresh install of LAMPP, you will need to install the SimpleXML extension. To do that, enter:

 sudo apt-get install php-xml

Step 6 – After that, restart the LAMPP services:

sudo ./lampp restart

Step 7 – final step. Check again:

symfony check:requirements

If needed, you can install the mbstring and intl extensions with the following commands:

sudo apt-get install php-mbstring
sudo apt-get install php-intl

To get PDO drivers for mySQL, type: 

sudo apt-get install php-mysql

That’s it, you should be good to go now.
