Re: [PHP] Where am i screwing up?

Can someone correct me on this if i'm wrong.......

try (meaning, I think that $vars as $keys will put the value into $key,
not the key itself):

foreach ($vars as $key=>$value) // clear all previous sessions
{
if(isset($_SESSION['$key']))
{
unset($_SESSION['$key']);
}
}
