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. http://www.php.net/manual/en/language.types.string.php#language.types.string.parsing Cheers, Torben > If you don't like doing it this way, do something like > > $PHP_SELF = $_SERVER['PHP_SELF']; > $form_block = "<form method=\"post\" > action=\"$PHP_SELF\">"; > > > HTH > > Erik -- Torben Wilson <torben@php.net> http://www.thebuttlesschaps.com http://www.hybrid17.com http://www.inflatableeye.com +1.604.709.0506
