My PHP Development Setup
I've struggled for years for a decent PHP IDE, I've used everything from nano, to vi to Eclipse, I even developed my own in PHP using wxwidgets (wxphp) which fell to the wayside when PHP7 came along and the support for wxwidgets was dropped.  I used PHPStorm a couple of times but had various issues and finally I have settled on Atom[1] which in the almost 20years I've been developing in PHP must say is hands down the best IDE for PHP yet... and it's free.[1] https://atom.io
