Another PHP casting weirdness

Second weird PHP behavior behavior of the day :

$foo = false;
echo $foo['bar']; // Ouptuts nothing, but doesn't throw an error either

Strange. I try to read an undefined index (falseis not an array), but PHP doesn't complain. That's weird.

$foo = true;
echo $foo['bar']; // Throws an error

This time, PHP tells me that the index is not defined and throws an error. Wait, what ?

Apparently, this is the intended behavior, but it does seem a bit strange...
