Question

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!

Answer 1

foreach($_SESSION as $key => $val){
    if(substr($key,0,5) === "cont_"){
        unset($_SESSION[$key]);
    }
}
