PHP sample codes on websites

How do you have PHP sample codes on .php pages that don't process? <code></code> doesn't work. I would like output like this:

<?php
echo "sample";
?>

Without it echoing anything and <?php being displayed.

You need to use htmlentities() so that things like < > are not interpreted by the browser and are instead treated as literal characters and are displayed.

Thanks CFMaBiSmAd ..... htmlentities() is on page 379 of my PHP book and I will look into it.

also there is PHP classes out there that will put your code into colour coded output just like it does on these forums i think i seen one on phpclasses.org a while ago.

show_source(); ? But then thats for an entire page.

i thought of that but as he mentioned sample code i thought i would direct him in a class...
