For compatibility and reusability of your code, PSR1 recommends that a file should introduce either new symbols (like classes, functions, etc.) or have side-effects (like outputting something, or including other files), but not both at the same time. The first symbol is defined on line 16 and the first side effect is on line 4.

if ( ! defined( 'ABSPATH' ) ) {
