Sherif Ramadan 98c9e56ef0 Merge branch 'pull-request/287' ...

Add ability to use array keys with array_filter().
This adds a third (optional) argument to array_filter() that will determine
what gets passed to the callback, the array key, value or both.
The third argument can be one of two constants: ARRAY_FILTER_USE_BOTH or,
ARRAY_FILTER_USE_KEY.
