Nope.  Quoted array indexes don't work inside strings.

Nope.  The {} don't change the quoting issues you mentioned in your first 
(non-working) example.

... and fails for the same reason!

You can use:

   echo "This script is called {$_SERVER['PHP_SELF']}";
   echo "This script is called ${_SERVER['PHP_SELF']}";
   echo "This script is called $_SERVER[PHP_SELF]";

or even 

   echo "This script is called " . $_SERVER['PHP_SELF'];
