Fixed.

I can confirm actual and expected are flipped in PHP, leave the issue open and after one week we can fix it.

Yes, PHP.

I am geting Kebab case in every instance.

Always state the language when the kata has more than one, is it PHP?

Test results:

INPUT "yInVxi"

Failed asserting that two strings are equal.
Expected: 'in-vxi'
Actual : 'y-in-vxi'

Actual and expected seem to be switched around as I am returning: 'in-vxi'

A vertical tab is a ASCII character between 32 and 126. So it is intended to be there. Please change your code to accomadate this.

This random test inputs a vertical tab symbol into actual results, finding my solution as invalid. Example tests pass just fine.

Please "unroger" the random test, it is adding line endings that should not be there.

Another error in this app!

The output shows a Vertical Tab symbol, resulting in an error. Vertical tab is a valid whitespace character.
Frustrating to find the solution without any credit.

Looks like codewars is just going to ignore the bug in their software.

Paranthesis is broken. I wonder how many other kata's don't work correctly. Support for this site seems non-existent.

I' getting the error:

'(())())' should equal ')())())'

but in my understanding it shoud result in '))))))'

paranthesis test is failing.

The output is correct from my local IDE.
