Modern Debugging Strategies (or, what to do when your code plays tricks on you)

Well done. Dan started with the basics of print_r and var_dump and worked our way through xdebug and phpunit, 3rd party toolbars and services, and showed us psysh and other tools to make figuring out what is going on behind the scenes a little easier when things go wrong or go not quite as expected.

I learned a few new things that I will need to revisit his slides to explore further.

Dan did an excellent job with the presentation - thank you! He explained everything well. I wasn't previously aware of the difference between the print_r and var_dump functions, but the details on both cleared that up for me.

Dan did a fantastic job covering the full range of day-to-day debugging options for developers. I really like how he started simple with echo/var_dump and made it to XDebug for step debugging. I even learned about a few new libraries that don't require a framework. The only thing he could have touched on was debugging PHP itself when it crashes. Seriously, everything else was covered!
