Problem CSS/HTML/PHP

[wacked]

also ich mache es so:

function browser_info($agent=null) {
  // Declare known browsers to look for
  $known = array('msie', 'firefox', 'safari', 'webkit', 'opera', 'netscape',
    'konqueror', 'gecko');

  // Clean up agent and build regex that matches phrases for known browsers
  // (e.g. "Firefox/2.0" or "MSIE 6.0" (This only matches the major and minor
  // version numbers.  E.g. "2.0.0.6" is parsed as simply "2.0"
  $agent = strtolower($agent ? $agent : $_SERVER['HTTP_USER_AGENT']);
  $pattern = '#(?<browser>' . join('|', $known) .
    ')[/ ]+(?<version>[0-9]+(?:\.[0-9]+)?)#';

  // Find all phrases (or return empty array if none found)
  if (!preg_match_all($pattern, $agent, $matches)) return array();

  // Since some UAs have more than one phrase (e.g Firefox has a Gecko phrase,
  // Opera 7,8 have a MSIE phrase), use the last one found (the right-most one
  // in the UA).  That's usually the most correct.
  $i = count($matches['browser'])-1;
  return array($matches['browser'][$i] => $matches['version'][$i]);
}

sagt mir welcher browser benutz wird.
und dann einfach:

$ua = browser_info();
  if ($ua['msie'])
    echo "<div id=\"footerIE\"><b>Layout by V!ruS</b></div>\r\n";
  else 
    echo "<div id=\"footer\"><b>Layout by V!ruS</b></div>\r\n";

das ist alles c&p code aus dem internetz. ich weiß nichmehr wo her ich es habe aber es funktioniert sehr gut. vielen dank an den coder.
