I've look and found this

PHP Code:

// [QUOTE]
    $bbcodes['custom']['find']['[quote]'] = '#\[quote\](<br>|<br />|\r\n|\n|\r)??(.*)(<br>|<br />|\r\n|\n|\r)??\[/quote\]#esiU';
    $bbcodes['custom']['replace']['[quote]'] = "handle_bbcode_quote('\\2')";
    $bbcodes['custom']['recurse']['quote'][0] = array('handler' => 'handle_bbcode_quote');

    // [QUOTE=XXX]
    $bbcodes['custom']['find']['[quote='] = '#\[quote=(&quot;|"|\'|)(.*)\\1\](<br>|<br />|\r\n|\n|\r)??(.*)(<br>|<br />|\r\n|\n|\r)??\[/quote\]#esiU';
    $bbcodes['custom']['replace']['[quote='] = "handle_bbcode_quote('\\4', '\\2')";
    $bbcodes['custom']['recurse']['quote'][1] = array('handler' => 'handle_bbcode_quote'); 


[php]
// [PHP] - this is the first custom tag because it does weird things to HTML
$bbcodes['custom']['find']['[php]'] = '#\[php\](<br>|<br />|\r\n|\n|\r)??(.*)(<br>|<br />|\r\n|\n|\r)??\[/php\]#esiU';
$bbcodes['custom']['replace']['

PHP Code:

'] = "handle_bbcode_php('\\2')";
        $bbcodes['custom']['recurse']['php'][0] = array('handler' => 'handle_bbcode_php'); 


So how would i go about this?
