To execute any code contained within a string you need to eval() it. Assuming you have this piece of code $uname = 'Leo'; $text = "<b>Hello there, <?php echo \$uname; ?></b>"; eval("?>$text<?php ;"); Note that you first escape from PHP in order to correctly "execute" plain text. >2.

Yes. See http://www.vogelsinger.at/test.php for an example (will be available for 1-2 days). -- >O Ernest E. Vogelsinger (\) ICQ #13394035 ^ http://www.vogelsinger.at/
