Right now, I'm receiving the following error when trying this on PHP:

PHP Parse error: syntax error, unexpected ',', expecting variable (T_VARIABLE) in /home/codewarrior/run.php on line 5

The Kata code is only 3 lines, and no matter what I change in the test section, the error remains.

That's the whole point of this Kata - you have to edit the code itself (not the tests) until there is no longer a syntax error ;)
