Appreciate man, you saved my day. I spend almost 5 hours on making it work. Thanks God I saw your comment and rewrote the whole thing to JS

Some tests against storing the argument globally would be nice.

Nice! This is much cleaner than my solution. I like the useage of reduce and replace. I will have to remember to use these more often.

Issue still not fixed :/

Please fix PHP tests, my code produce the same thing as my javascript code, but my javascript code pass all the tests..
