is possible change configuration of yii, to: 1- make yii , database accessible outside folder 'protected' 2- send data outside folder 'protected' files inside 'protected' or there other solution ? thank help. it possible since protected folder protected .htaccess file. if eliminate "defensive rules" , have right directory/file permissions, protected folder can made accessible outside. however recommend not this, because direct access protected folder (as name suggests) should made inaccessible standard users.

i have entity millions of instances. each instance has reference ordered list of items . lists have unique no list stored more once. once created, both lists , entity instances immutable. there far more entity instances lists , , database has support fast insertions of entities . so what's insert-efficient, robust, way of storing immutable , unique , ordered lists ? edit: far, i've considered these approaches: 1) lists table has these columns: <list_id> <order> <item> if list #5 contains elements [10,20,30] table contain: 5 1 10 5 2 20 5 3 30 the entity table have item_list_id column references lists table (it's not foreign key since list_id not unique column in lists table - the can solved adding table single column contains valid list_ids ). this solution makes inserts bit tricky it places responsibility enforcing uniqueness of lists on application, isn't great. 2) lists table has these columns: <...
