$str=preg_replace("/s+/", " ", $str); //过滤多余回车
$str=preg_replace("/<[ ]+/si","<",$str); //过滤<__("<"号后面带空格)
$str=preg_replace("/<!–.*?–>/si","",$str); //注释
$str=preg_replace("/<(!.*?)>/si","",$str); //过滤DOCTYPE
$str=preg_replace("/<(/?html.*?)>/si","",$str); //过滤html标签
$str=preg_replace("/<(/?head.*?)>/si","",$str); //过滤head标签
$str=preg_replace("/<(/?meta.*?)>/si","",$str); //过滤meta标签
$str=preg_replace("/<(/?body.*?)>/si","",$str); //过滤body标签
$str=preg_replace("/<(/?link.*?)>/si","",$str); //过滤link标签
$str=preg_replace("/<(/?form.*?)>/si","",$str); //过滤form标签
$str=preg_replace("/cookie/si","COOKIE",$str); //过滤COOKIE标签
$str=preg_replace("/<(applet.*?)>(.*?)<(/applet.*?)>/si","",$str); //过滤applet标签
$str=preg_replace("/<(/?applet.*?)>/si","",$str); //过滤applet标签
$str=preg_replace("/<(style.*?)>(.*?)<(/style.*?)>/si","",$str); //过滤style标签
$str=preg_replace("/<(/?style.*?)>/si","",$str); //过滤style标签
$str=preg_replace("/<(title.*?)>(.*?)<(/title.*?)>/si","",$str); //过滤title标签
$str=preg_replace("/<(/?title.*?)>/si","",$str); //过滤title标签
$str=preg_replace("/<(object.*?)>(.*?)<(/object.*?)>/si","",$str); //过滤object标签
$str=preg_replace("/<(/?objec.*?)>/si","",$str); //过滤object标签
$str=preg_replace("/<(noframes.*?)>(.*?)<(/noframes.*?)>/si","",$str); //过滤noframes标签
$str=preg_replace("/<(/?noframes.*?)>/si","",$str); //过滤noframes标签
$str=preg_replace("/<(i?frame.*?)>(.*?)<(/i?frame.*?)>/si","",$str); //过滤frame标签
