I know this is a dated article but regarding isset I feel the need to point out the difference between a language construct and a function!
isset isn't a function but a language construct, if you don't know the difference look it up.
TLDR: isset is a lot faster than even built-in functions as is_null. So imho isset should always be preferred cause performance does matter even for websites with moderate loads but certainly for any processing however light.
