Session variables not resetting

Question

I'm having trouble resetting session variables in PHP. I'm now trying just testing resetting the session variable like this, but this doesn't even work:

session_start();
$_SESSION["name"] =false;
if (!isset($_SESSION["name"])) {
  $message = getname(); //can't get this to ever be called
} else {
  $message = welcome();
}

What am I missing here?

Answer 1

You want to unset the session variable

unset($_SESSION['name']);

Setting it to false makes it so it's still set (so isset will still return true), the only difference is that the actual value of the variable has changed to false.
