From what I have been able to glean from forums it can be a
nightmare. I found this bit on StackOverflow:
$_SESSION[x] = 123;
$x = 'asd';
echo $_SESSION[x];
The output will be asd if register_globals is on.
I was doing the equivalent of $x=$_SESSION['x'] for the second line
which made it a double whammy. It seemed reasonable, tidy and easy to
keep track of to use the same name for the regular variable as the
_SESSION variable. I do that with _GET and _POST sometimes, too. At
least it turned out to be easy to turn register_globals off once Jerry
had pointed me there.
