Answer Posted / p .g .senthilkumar
isset -> this variable handling functions determine whether
a variable is set . It checks whether a variable is set
even though it is empty.
empty -> as the term itself has already given a sign that
it would related to something that's empty, this variable
handling functions determine whether a variable is empty.
It checks whether a variable has a value whether it's empty
string, zero(0), or not set at all.
