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.

Yes. See http://www.vogelsinger.at/test.php for an example (will be
available for 1-2 days).
