$_GET may not handle query string parameter values which include escaped Unicode values resulting from applying the JavaScript "escape" function to a Unicode string.
To handle this the query parameter value can be obtained  using a function such as:

function getQueryParameter ($strParam) {
  $aParamList = explode('&', $_SERVER['QUERY_STRING']);
  $i = 0;
  while ($i < count($aParamList)) {
    $aParam = split('=', $aParamList[$i]);
    if ($strParam == $aParam[0]) {
      return $aParam[1];
    }
  }
  return "";
}

or by directly building an array or query string values and then processing the parameter string using a function such as the "unescape" function which can be found at http://www.kanolife.com/escape/2006/03/unicode-url-escapes-in-php.html (or http://www.kanolife.com/escape/ for related info).

Note that it's a very, very bad idea to append to global variables in a loop, unless you really, really mean to do so in a global context. I just a while ago hung my server with a snippet of code like this:
