PHP 链接参数如何加密(验证)
我要是对显示出的一条记录进行删除，一般的做法就是把“删除”作为一个链接，链接的地址比如：http://121.121.121.121/del.php?id=$id，在del.php中接收id这个参数传来的值。
那么这样的话，我就可以直接在url里输入比如：http://121.121.121.121/del.php?id=43，对id是43的记录进行删除了，这样很不安全。
我看其他网站的相似的链接，参数中会有一个好几十个字母长的一个大的字符串，我想这个可能就是起到验证的作用吧。
那么验证部分该怎么写？或者说思路是什么？
谢谢。
------解决方案--------------------
这个删除肯定要有权限才能删除，不是随便一个人就可以删除的吧。。。
------解决方案--------------------
del.php页面要设置一个访问权限，比如session或cookie判断
------解决方案--------------------
也可以点删除之后用js以post的方式传参数，这样就不会暴露在url里了
------解决方案--------------------
。。。你删除页面至少也得判断个session["user"]，看看这个请求是不是登陆用户吧？
另外对于URL加密来说，你可以找PEAR里别人写的现成加密程序，再稍微改动一点点，成为你独自的加解密程序。
