Auto increment number for multiple lines in PhpStorm

Update: This feature is now available in the String Manipulation plugin v4.5

Old: It's far from ideal, but you can use the Duplicate and increment action from the String Manipulation plugin. It's quite easy to do and it does the job:

Add a shortcut to this action or execute it multiple time to increment a line containing a number.

So far no PhpStorm plugin allows to do exactly what to describe.

It may be the occasion to create one !

String Manipulation* is the name of the addon (as already mentioned by Xedecimal).

Create sequence is the name of the action you want to use. (This does exactly what you want!)
