Xdebug is a tool used by developers and people who hunt bugs to find bugs in the code. It could be very useful sometimes, espessially if the bugs are hard to find quickly.
It can be a bit confusing if you never tried to install Xdebug before. One guy in our team struggled with it for some hours before he found out how to install it. And as usual, you think you look for some advanced command or something, and it always turns out that it was just a “one-liner”. It doesen’t get easier than this.
Ubuntu Server 12.04
Write this in terminal:
:~$ sudo apt-get install xdebug
Then Ubuntu will activate it by itself. Wow, we just love Ubuntu!
Don’t forget to restart you apache
:~$ sudo services apache2 restart
