php在做敏感词过滤时怎么解决用特殊符号分割、简繁体、半角全角,来绕开过滤的问题?
彻底地过滤敏感词

彻底地过滤敏感词
过滤和谐词其实并不是一个好策略,有一万种说出敏感词的方法,就一定会有第一万零一种,如果你反复设置程序去和谐这些词,最后会发现,你的会员连最基本的一些话都不能发了。和谐没有终极解决方案,却能最终作茧自缚,自缚双手。对付这些内容最佳的方案还是靠人工,如果你的系统用户比较多,信息产生得比较快,可以参考参考微博的社区委员会制度,通过发动一些热心的会员来辅助管理内容。

上有政策 下有对策
很难通过程序完全过滤全部敏感词(特殊分隔、简繁等)
你需要正则表达式。
<code>$content = "新开的淘[防和谐]宝网店欢迎光顾!"; preg_replace('/淘.{0,6}宝/uU', '****', $content);</code>
用以上的正则表达式,只要“淘”和“宝”中间有0到6个字符,管你什么字符,照和谐不误。
更多用法请自行学习正则表达式。
这种要看策略了,不过大部分的都还是机器+人工的方式来处理,没法用机器100%处理掉敏感信息
关键词过滤容易误杀,而且总有方法绕过,所以只能用来做初步过滤,最终还是要靠人工来审核
