The Debug Dance - An Intro to Step Debugging - php[tek] 2017

The Debug Dance - An Intro to Step Debugging - php[tek] 2017

This talk was given at php[tek] 2017.

Using `var_dump()` to debug your app has its benefits, but there are more comprehensive and efficient ways to debug those particularly elusive bugs. Enter step debugging. We’ll be using the PhpStorm IDE to step through our PHP apps line by line and see how much more power step debugging gives us over the conventional `var_dump()` technique. We'll also touch on debugging from the command line. Learn to dance in PHP with step debugging.
