The magic works by assigning a name to the operation - names are very powerful magic.

Personally, I find: 

if ($zipcode == 12345 || $zipcode == 55344 || $zipcode == ...) {
  code
}

much harder to understand than
if (is_valid_zipcode($zipcode)) {
  code
}

specially when it comes to better understanding of what the code is meant to accomplish.
