More over desciption story is utmost interesting, I giong to share it with my firends.

Thank you.

@Chrono79, I had fixed that mistake already.

Nice task need to read description better.

Thank you for this task.

Poorly described task, "in place sorting" does not mentioned, incorrect bolier plate code template.
In this task need to sort array in place. But function signature does not use references in the PHP translation.

I am really curious where does this sorting break any condition of "wave sort":
5454>=1<=65>=2<=65>=4<=34>=4<=6>=5<=5>=5 ? UPD: This sort is correct, but need to sort inplace.

Really informative messages in tests. Nice kata.
Thank you.

Helpful comment, thank you.
