Re: Function not returning

Thanks, that all works now.

Can you explain though why it wasn't returning $reply?


It was, but you didn't store the output. When a function returns something, it's not magically stored into a global variable.

For this you can use a reference, the global keyword or the $GLOBALS array.

Perhaps you should examin the section that describes functions in the online manual more closely (especially regarding returns from functions):
