Sorry, but I do have to correct you here--this isn't true. ;) In double-
quoted strings and heredocs, you can do the following:
$foo = "This page is $_SERVER[PHP_SELF]";
Or, better:
$foo = "This page is {$_SERVER['PHP_SELF']}";
You do have to concat to do this in single-quoted (noninterpolated)
strings, though.
