Warning I'm a total newbie at both php and any type of coding at all. I was hoping someone could explain a line of code in a for loop for a php/mysql tutorial that I I've been trying to do. The following is the loop:
My guess is this formats the output and calls the variables that will display in the echo $rString."&"; I guess what I don't understand is partially syntax related. I understand that the stuff with $ in it are variables and the stuff in the [ ] refers to items in the array but I don't understand what the stuff with the ampersand is doing. Also why does the = sign have to be in quotes? Thanks.
