You are echoing the return of array_walk which is true and echos as 1.

Hi Gang:
I had an odd thing happen with using the PHP array_walk() function.
The problem is demonstrated below:

What’s with the “1” appearing after the array_walk() function?
Please review the above URL before offering comment. I don’t believe the function should work that way.
Many thanks in advance for any answer.
Thanks,
