How To Install xdebug on PHP 7.1

in Testing

Xdebug is a very useful tool when it comes to PHP development, it's a PHP extension that allows you to profile and debug your PHP code. It even allows you to step through your code during runtime to see how it is behaving.

I use PHPStorm for my PHP development and when running this with xdebug I'm able to step through the code during runtime inside the IDE and trace the entire application. I mostly use this during writing my unit tests where I can step through the code and see any errors.

XDebug is also useful to create code coverage reports using the following library.
