Display HTML code with PHP

[Billy]

As you probably all know, we can display code here in <pre><code></pre></code> tags.
But how can we do that on our own pages without using <xmp> (outdated) ?

I guess it can be done with htmlentities(), but how can I make the <code> tag always have text within it run through htmlentities() first so as to display the tags?

The code would seem to suggest that, but when I was looking for this on the internet (how to display the code) I heard about prettify only making the text a different colour and not showing the code (unless escaped).
I’ll give it a try.
