[BBCode problem]

Hi there!

Can anybody here tell me how to make

 BBC which will disable any code parsing (BBCode, HTML - to display both without parsing it) and tell me, which font to use with it?
Thanks !!!

But I think you can do something like this via Ajax.

[PHP highlight]

HELP PEOPLE!
Hi everyone. I have next BBCode:
[CODE]
        $PHPCodeLayout = '<table width="90%" border="0" align="center" cellpadding="0" cellspacing="0" background="images/code.jpg">
                                <tr>
                                    <td><span class="quotecodeheader style1">PHP kod: </span></td>
                                </tr>
                                <tr>
                                    <td background="images/code.jpg">'.
highlight_string(stripslashes('$1'), true).'</td>
                                </tr>
                          </table>';
            // Check for [code=php:0] text

            $Text = preg_replace("/\[php\](.+?)\[\/php\]/is","$PHPCodeLayout", $Text);
[/CODE]
So, what is the problem?
