I was wondering.. how exactly does the isset function work? I saw that Robert Cummings wrote: $page = isset( $_GET['page'] ) ? $_GET['page'] : null; What exactly does that mean? isset function checks if a given variable is set or not, in above line of code you are seeing its use with operator (?). What it will do: It will check if there is any variable with named $_GET['page'], it is true then it will assign the value of $_GET['page'] to $page variable, otherwise it will be set to null value. You are 14?? Welcome to the wonderfull world of PHP programming.
