I think that this is only important when using an associative array
element reference within certain kinds of quotes. Like this:
// this won't work b/c of quoting issues
echo "This script is called $_SERVER["PHP_SELF"]";
// this should work fine IIRC
echo "This script is called $_SERVER['PHP_SELF']";
// this should also work if for some reason you needed
// to use double quotes within the array element reference
// (to interpolate a variable, for instance)
echo "This script is called {$_SERVER["PHP_SELF"]}";
// and this is the same thing really
echo "This script is called ${_SERVER["PHP_SELF"]}";
