i am new to Sencha. im developing an app where it connects to Mysql db and pulls some customers from customer table (eg. cust_code, cust_name) and populates a list on load.

it then stores this list offline and user can add a new customer or edit an existing one and this later gets synced to mysql db.

do i need to know php for this? what options do i have? please give me some examples..

please help.
