The kings of IDEs! Again they have shown how awesome they are and are stepping up to provide support for this growing PHP community.
If you are not using a JetBrains IDE yet it's probably only because you have not seen it yet.
All the organizers of JoburgPHP instantly fell in love with their products and have since then tried to convert as many developers as we possibly could.
If you are big into PHP development it is highly recommended that check out their "Lightning-smart PHP IDE", PhpStorm.
