场景:

       项目迁移后 初始化角色的权限

案列解析:

       代替了array_filter， 没啥必要性不这样话的也可以的     

Collection::macro('forOperator', function() {
    return $this->filter(function ($value) {
        return preg_match(
            '/(add|edit|view|delete) (customer|service|fund|charge|profile)/',
            $value
        );
    });
});
$operator = Role::create(['name' => 'operator']);
$operator->givePermissionTo(Permission::all(['name'])->forOperator()->toArray());
