Hi,
I am just screwing around and getting used to arrays with a foreach thanks
to Michael,Jan and Evan from this list and have run into problems.
My requirment is pretty simple (code is below too)
1)unset all the sessions that might have been set with reference to the
hardcoded array ($vars)
2)if
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']);
}
}

No need to loop here, you can use an else statment in the next
loop. And
