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'];
