Eclipse — Add Space After Square Bracket (Formatter)

What I am looking for is very similar to what can be found here: Eclipse: Adding Spaces to Parentheses

However, I also need to do this for square brackets.

For example:

array[index] => array[ index ]

Thank you in advance.

Answer

It can be done as in the referenced answer but on Whitespace -> Arrays section.
Remember to work on a copy of the built-in formatter using the New button for backup purposes .
