$str=preg_replace("/\s+/", " ", $str); //過濾多余回車
$str=preg_replace("/<[ ]+/si","<",$str); //過濾<__("<"號后面帶空格)
$str=preg_replace("/<\!–.*?–>/si","",$str); //注釋
$str=preg_replace("/<(\!.*?)>/si","",$str); //過濾DOCTYPE
$str=preg_replace("/<(\/?html.*?)>/si","",$str); //過濾html標(biāo)簽
$str=preg_replace("/<(\/?head.*?)>/si","",$str); //過濾head標(biāo)簽
$str=preg_replace("/<(\/?meta.*?)>/si","",$str); //過濾meta標(biāo)簽
$str=preg_replace("/<(\/?body.*?)>/si","",$str); //過濾body標(biāo)簽
$str=preg_replace("/<(\/?link.*?)>/si","",$str); //過濾link標(biāo)簽
$str=preg_replace("/<(\/?form.*?)>/si","",$str); //過濾form標(biāo)簽
$str=preg_replace("/cookie/si","COOKIE",$str); //過濾COOKIE標(biāo)簽
$str=preg_replace("/<(applet.*?)>(.*?)<(\/applet.*?)>/si","",$str); //過濾applet標(biāo)簽
$str=preg_replace("/<(\/?applet.*?)>/si","",$str); //過濾applet標(biāo)簽
$str=preg_replace("/<(style.*?)>(.*?)<(\/style.*?)>/si","",$str); //過濾style標(biāo)簽
$str=preg_replace("/<(\/?style.*?)>/si","",$str); //過濾style標(biāo)簽
$str=preg_replace("/<(title.*?)>(.*?)<(\/title.*?)>/si","",$str); //過濾title標(biāo)簽
$str=preg_replace("/<(\/?title.*?)>/si","",$str); //過濾title標(biāo)簽
$str=preg_replace("/<(object.*?)>(.*?)<(\/object.*?)>/si","",$str); //過濾object標(biāo)簽
$str=preg_replace("/<(\/?objec.*?)>/si","",$str); //過濾object標(biāo)簽
$str=preg_replace("/<(noframes.*?)>(.*?)<(\/noframes.*?)>/si","",$str); //過濾noframes標(biāo)簽
$str=preg_replace("/<(\/?noframes.*?)>/si","",$str); //過濾noframes標(biāo)簽
$str=preg_replace("/<(i?frame.*?)>(.*?)<(\/i?frame.*?)>/si","",$str); //過濾frame標(biāo)簽
$str=preg_replace("/<(\/?i?frame.*?)>/si","",$str); //過濾frame標(biāo)簽
$str=preg_replace("/<(script.*?)>(.*?)<(\/script.*?)>/si","",$str); //過濾script標(biāo)簽
$str=preg_replace("/<(\/?script.*?)>/si","",$str); //過濾script標(biāo)簽
$str=preg_replace("/javascript/si","Javascript",$str); //過濾script標(biāo)簽
$str=preg_replace("/vbscript/si","Vbscript",$str); //過濾script標(biāo)簽
$str=preg_replace("/on([a-z]+)\s*=/si","On\\1=",$str); //過濾script標(biāo)簽
$str=preg_replace("/&#/si","&＃",$str); //過濾script標(biāo)簽
