Code Filter

This module provides a simple text format (input filter) that handles <?php ?> and <code></code> tags so that users can post code without having to worry about manually escaping < and > characters with &lt; and &gt;

For PHP code, this module also adds syntax highlighting. For example:

print "Hello, world!";
