Comment (by hellofromTonya):

 @SergeyBiryukov What do I think?

 Type casting code: it's more concise with less lines of code, but IMO less
 understandable for what happens and why with different values or lack of
 value.

 Why? When I read it, my first thought is: why is it type casting and doing
 the processing when there are no emails to be processed.

 I'd vote for the empty/is_array version for quick understanding and
 eliminating unnecessary processing.
