In the example listed above: <?php $foo = 'Bob'; // Assign the value 'Bob' to $foo $bar = &$foo; // Reference $foo via $bar. $bar = "My name is $bar"; // Alter $bar... echo $foo; // $foo is altered too. echo $bar; ?> the documentation above it is somewhat ambiguous: $bar = &$foo means that $foo becomes the reference for $bar, thus $foo = "Bob". As I read it, $bar should've become the reference for $foo, took me a bit to turn it around. Just some clarification.
