PHP URL参数检测问题
函数如下:
<code>function check_name($action) { if(strpos($action, '__') !== false || strpos($action, '--') !== false) return false; return preg_match("/^[a-z0-9]{1}[a-z0-9_\-]{0,}[a-z0-9]{1}$/", $action); } </code>
$action是URL参数,这样做有什么意义呢?

个人觉得可能是—__这种的多为私有方法,这样访问可能确保不会访问到私有的action吧
不就是验证一个字符串是不是符合规则么 完了呢?
