[Help] BB Code

[JayC]

I need 2 things regarding BB code and I am not really sure how it works.

1) BB Code -> HTML Code

 public static function BBcode($text)
    {
      $bbcode = array("<", ">",
                "[list]", "[*]", "[/list]",
                "[img]", "[/img]",
                "[b]", "[/b]",
                "[u]", "[/u]",
                "[i]", "[/i]",
                '[color="', "[/color]",
                "[size=\"", "[/size]",
                '[url="', "[/url]",
                "[mail=\"", "[/mail]",
                "[code]", "[/code]",
                "[quote]", "[/quote]",
                '"]');
  $htmlcode = array("&lt;", "&gt;",
                "<ul>", "<li>", "</ul>",
                "<img src=\"", "\">",
                "<b>", "</b>",
                "<u>", "</u>",
                "<i>", "</i>",
                "<span style=\"color:", "</span>",
                "<span style=\"font-size:", "</span>",
                '<a href="', "</a>",
                "<a href=\"mailto:", "</a>",
                "<code>", "</code>",
                "<table width=100% bgcolor=lightgray><tr><td bgcolor=white>", "</td></tr></table>",
                '">');
  $newtext = str_replace($bbcode, $htmlcode, $text);
  $newtext = nl2br($newtext);//second pass
  return $newtext;
    }

Still Returns BB Code

2) BB Code Toolbar

Thanks Guys
