#用户发布的html,过滤危险代码
复制代码 代码如下:
function uh($str)
{
$farr = array(
"/\s+/", //过滤多余的空白
"/]*?)>/isU", //过滤 <script>"/(<[^>]*)on[a-zA-Z]+\s*=([^>]*>)/isU", //过滤javascript的on事件 <BR>); <BR>$tarr = array( <BR>" ", <BR>"＜\\1\\2\\3＞", //如果要直接清除不安全的标签，这里可以留空 <BR>"\\1\\2", <BR>); <BR>$str = preg_replace( $farr,$tarr,$str); <BR>return $str; <BR>} <BR>
</script>
