php - Collecting continuous rating data array from a slider or dial on a web page -


we need create web page control (a slider or dial), , need collect continuous data users adjust control on time. example, if user stays on page 1 minute , continuously adjust level of slider or dial , down, we'd value of slider or dial every 1 second (so end array of 60 values in case).
in past, have collected single value user using dxhtml slider , basic php form processing. works great. however, gives single value -- value of slider when hit submit.
need array of values. we'd have array passed our php processing code when user done page, perhaps when hit done or submit button. in sense, our needs not continuous/real time -- need have user input data continuously , keep track of somehow, don't need process until user done page , hits done or submit. we'd in 'lightest' way, using simple javascript/php if possible rather complex analytics packages. not sure if there existing libraries doing sort of thing -- hope so. thank help.

thanks
