It used to be that if you did this:
$foo[bar] = true;
instead of:
$foo['bar'] = true;
you would get a 'Notice' error. However now with PHP 5, I no longer seem to get this error? Has this been changed?

In fact, this question has nothing to do with arrays. It's string bar
you're typing against rules, as strings should be always quoted in PHP.
While array keys has nothing to do with quotes. In PHP you can use almost every language construct that returns scalar value to be used as a key. Only square brackets belongs to array syntax. Everything between them is just going to be regular PHP expression with it's usual rules.

They still trigger that notice, so you must have disabled notices from being displayed on screen.

Probably error reporting is turned off.
Try at top of the code:
ini_set("display_errors", true);
error_reporting(E_ALL);
