accidentally submitted while testing 🤦🏻‍♂️(still ocassionally fails)

done

In PHP the assertions all have their 'Actual' and 'Expected' reversed, which made the expectations ins the random tests very hard to understand..since it was my own incorrect output.

Darn, I tried a similar solution with preg_replace(), but with var_export() instead of print_r() and it ouputted something like "no shortcuts allowed".
Didn't think to go further down that route.
