        // Array containing the names:
        $names = array( 'Shaun', 'Eric', 'Sarah', 'John', 'Barry', 'Dave', 'Zach', 'Helena' );

        // Calls our function, sending the array:
        showNames( $names );
        echo '<br />';
        sort( $names, SORT_ASC );
        echo    'And now this should be sorted alphabetically (A - Z): <br />';
