I wasn't aware it even existed until now and I don't really see the point of
it.  If you want to use data that is in the $_SESSION array why not just use
isset or as you said a simple if condition (although it does give a nice PHP
notice if it the $_SESSION variable does not exist yet).  Maybe it is from
an earlier era when $_SESSION didn't exist yet.  It seems to work and
doesn't hurt anything but I will probably forget about after today and keep
using isset.
