Array Key Indentation about php-mode HOT 1 CLOSED

The example in the README is intended to demonstrate a different aspect of the indentation: the treatment of the closing parentheses. I aligned the => operators out of habit, which I do by using align-regexp bound to a key. But I did not consider the potential confusion in the example until you brought this up. I can see how a person may think that php-mode automatically aligns things by =>. Since that is not the case I have changed the example in the README.

Adding a rule to align-rules-list (available from M-x customize-group align) may be the easiest approach, although it would still require manually running M-x align to get the desired effect; or add a small hook to run align every time you save a file. The other approach that comes to mind is to change the behavior of two cc-mode properties, which is the engine that indents php-mode: arglist-cont and arglist-cont-nonempty. It should be possible to automatically align array contents by => by writing a custom line-up function to use with those two:

So that may be a good place to start if you want to implement such a feature. Although I am not an Elisp guru, and personally I think diving into cc-mode is the path to insanity, so hopefully someone else knows of an easier approach, lol.

Thanks for the bug report too, since I didn't notice that potential for confusion caused by the example.
