php正则问题eregi_replace("]+>", "")这样能替换恶意代码吗？
------解决方案--------------------
是的，过滤了Javascript或VBScript的代码，这个很重要，过滤掉iframe是为了不要让别人在你的网页嵌入一个框架，导致访问者被骗。
------解决方案--------------------
应该还有漏洞，假如别人不用<script>这种方法调用JS，比如一个表单<input onChange="alert('123');">，这种方法或在<a href...中的连接用javascript:alert('123');，一样会有漏洞，所以最好就是用htmlentities函数过滤掉所有的html特殊带有“<”“>”这种标记<br /><font color='#e78608'>------解决方案--------------------<br />自己测试一下就好了，最好的办法就是不能输入htlm，使用php的html函数<br />htmlentities<div class="clear"></script>
