Question

function checkSessionToken($token) {
  if (!isset($_SESSION['token']) || empty($_SESSION['token'])) {
    return false;
  }

  return $token == $_SESSION['token'];
}

For some reason this function is not returning any value, while it really should, causing my script to fail. When I put the result in a variable and echo it, I don’t get any output. Why is this?

Thank you

The code looks good.

Don’t echo the value. Use var_dump. echo false; does not output anything (example).

var_dump will output bool(false).
