I believe they recently added this to the latest IntelliJ release, and I would assume PhpStorm as well. As the bindings are system specific, take a look at http://blog.jetbrains.com/phpstorm/2014/03/working-with-multiple-selection-in-phpstorm-8-eap/. Looks like that version is available through EAP, so don’t know when they will release it for general consumption (or if they have already).
