PHP 7.2 Deprecated: Function Warning

Hi there

I see there is now a Deprecated: Function warning when using PHP 7.2 and setting up a backup schedule.

create_function() is deprecated in wp-content/plugins/wp-db-backup/wp-db-backup.php on line 1197

$all_tables = array_map(create_function('$a', 'return $a[0];'), $all_tables);

Any help on how this function should be coded would be appreciated by many.

Kind Regards
Brad
