Hey guys, I'm currently developing a billing app

Code:
$apps[$x]['description']['id'] = "Manajemen billing dan tarif untuk panggilan keluar.";
does not look like a valid entry. the entries are typically language-country.

Are you interacting with the existing v_providers table or are you creating a conflicting v_providers table? It looks like you are creating a conflicting v_providers table. Make sure you are not conflicting with existing tables when creating a table.
