I have the same issue with this kata on PHP.

We can't see your code, so please post it with a spoiler flag.

Fixed.

Spoiler flag, please.

@rowcased Sample tests are a requirement for kata. But there's already an issue about them so I won't reraise it.

• the function to fix is intended to convert a number to a string: toString
• this is a bugfix kata, so you do have to figure out what's wrong with it
• every language gets the same deal with no sample tests to encourage TDD
• raising issues is meant exclusively for when a kata isn't working correctly

See plOnion's post below. Neither his post nor my answer is marked as spoiler so you should be able to see them.

If two words have the same last letter, the returned array should show them in the order they appeared in the given string.

The original string was: 'what time are we climbing up the volcano'. You can see the expected is ok and the one you returned isn't. Also, it's been asked and answered before just a few posts below.
