e.g.

$Red = 'red';
$pRed = &$Red;
$RedToo = *$pRed;  <-- probably wrong :)

No, it's like this:

$Red = 'red'; // $Red == 'red' -> true.
$pRed = &$Red; // $pRed == 'red' -> true - this is not a C++ reference, it's more link a shortcut.
$RedToo = $pRed; // $RedToo == 'red' -> true.
$pRed = 'blue'; // $Red == 'blue' -> true, $RedToo == 'blue' -> false.

Does PHP have a version of the select case/switch statement?

In C++ it would be

--- Code: ---switch(variable)
 {
   case 1:
   //first selection
   break;
   case 2:
   //second selection
   break;
   default:
   //if nothing else matches
 }

--- End code ---

Usually, elseif is sufficient, but sometimes the switch comes in handy.

Yes, and it has exactly the same syntax.

I thought it might. I think jscript uses the same syntax also. That's one of the good things about learning C type languages.
