I know this is a really basic question, but I'm still a real php noob. I want to move $salt to the config.php file, but I'm not sure how to call the variable correctly so the page can use it.
I tried this:
require_once('config.php);
$salt = loadSaltFromConfig();
I'm assuming that I need to declare loadSaltFromConfig somewhere, but I'm not quite sure what that would need to be.
