Just to reiterate on what everyone has already said before, you should not use wrapper functions for
isset. Using a wrapper function will generate a Notice unless you pass the unset variable by
reference, in which case it is the equivalent to writing using $var === null (which is a lot
faster). Even if you do pass the variable by reference, you could still get notices using
multidimensional arrays where isset() would silently return false.
