[PHP] javascript VS php

[Miguel Loureiro]

Hello all
I would like to know if its possible from a javascript function call a php function 
(uiuiuiuiui...) ?
This because I have a bidimensional array, and when user select a option of a checbox, 
on javascript function I read the selectedIndex and want to see the values of that 
name ( see arr[selectedIndex] with for cicle).
If not possible(and I think it isnt), there is any solution?
TY all
Best Regards
