Use a foreach loop to iterate through an array…

you should use foreach to loop over arrays, however, to answer your question as to why your code isn’t working:

In PHP the integer 0 is falsy, the first element in your array is 0 so the while loop never executes (because the first condition is false), you would need to do a type-sensitive comparison to use while:

while (($a = current($num)) !== false) { ... }

Definitely use foreach though.
