That is cool This is not my post But you just showed me a new html tag I never knew of <xmp> It is cleaner then my textera box way.

Unfortunately <xmp> has been deprecated so there's no guarantee of it working in the future. <pre> is the recommended tag though it doesn't quite do what <xmp> does.

This one is in ASP VbScript

'Change code delimiters to HTML entities

    strItem = Replace(strItem,">","&gt;")
    strItem = Replace(strItem,"%","%")
    strItem = replace(strItem,chr(34),"&quot;")
toCode = strItem    
end function

Use would be

 response.write tocode("<h1>Blah</h1>")

PHP would be

PHP Code:

function toCode($strItem) {
           $html = array("<",">",chr(34));
           $entities = array("&lt;","&gt;","&quot;");
           $strItem = str_replace($html, $entities, $strItem);
return $strItem;
} 


Use would be

PHP Code:

echo toCode('<h1>Blah</h1>'); 


This is the post i'm sure you were referring to, after the Character Entities discussion we had.

Well you already have several answers on how to build it yourself, but you can also get a PHP script that does it for you (and more).

GeSHi - Supports syntax highlighting and many programming/markup languages and is highly customizable. I haven't personally used it, but my friend recommended it to me and his site used it (way back when I didn't know anything php).

Might give that a try

EDIT: Neat, you can even click on the tags and they link you to a definition and list parameters etc. I think I'm going to build something and put this to use now :P
