Question

I’m simply looking to loop through all current session variables and if the session variable name begins with ‘tmp’ then I want to unset the variable.

I would do it as follows:

foreach($session as $sv){
    if(substr($sv,0,3)=='tmp'){
        unset($sv);
    }
}

Just not sure how to get all the current session variables into an array to start with.

Thanks in advance!

What’s the problem with

foreach (array_keys($_SESSION) as $key) {
    if (substr($key,0,3) == 'tmp') {
        unset($_SESSION[$key]);
    }
}

?
