You need to echo $abc. The program is printing something else since you're echoing What's up within the method, remove that.

Correct, though don't delete the echo, just print $abc as that is your problem.

@Andy yes, rather I shouldn't have asked to delete the other echo statement :-D

@Rafee you don't need to remove the echo, but you should be echoing $abc which receives the return value from the method.

Exactly as you've done - although you call "kk()" twice, which is not nneeded, so drop line 13.
