Use a wild card to unset sessions with a prefix (php)?
===

I am using PHP to set session variables that all begin in cont_ so `$_SESSION['cont_`... now I cannot use `$_SESSION['cont']['subvariable'];` for a very server-related, specific reason. I tried doing `unset($_SESSION['cont_'*];` but that gives out errors.

What would the best way be to do this without having to set `$_SESSION['cont']['var'];`?

Thanks a lot in advance!
