From Activate Xdebug in VVV

Running xdebug_on inside Vagrant:

• Copy and paste output from phpinfo() to Xdebug wizard, analyze and check step about editing the php.ini file (step 9 in my case).
• Check if /usr/lib/php/*/xdebug.so is present in the VM (it should be):

$ ls /usr/lib/php/20170718/xdebug.so

• Update /etc/php/*/fpm/php.ini inside the Vagrant VM according to instructions from the Xdebug wizard website.

$ sudo tee -a /etc/php/7.2/fpm/php.ini >/dev/null <<'EOF'
 [xdebug]
 zend_extension = /usr/lib/php/20170718/xdebug.so
 EOF

• Restart php service

$ sudo service php7.2-fpm restart

• Check phpinfo()–it should contain a new section for Xdebug
