经常会遇到要获取上一页地址的路径。你可以返回上一页使用,实现这个是通过JS来操作的,下面有个不错的示例,大家可以参考下
实际在项目过程中,我们经常会遇到要获取上一页地址的路径。你可以返回上一页使用


<script>window.history.go(-1);</script>


这个是通过JS来操作的

如果出现这样的场景,当用户需要退出帐号,你又希望他退出后直接在返回当前页面

比如,当前页面的地址为http://xxx/module.php?module=groupbook&view=index&id=2.

你退出系统想必会使用 $_SERVER['REQUEST_URI'] 来 获取当前路径,然后把这个值做为参数传给退出需要返回的路径,这个时候你回发现

他只获取了http://xxx/module.php?module=groupbook 却没有得到&view=index&id=2,也就是说我们退出后返回的地址变成了

http://xxx/module.php?module=groupbook(本应该是http://xxx/module.php?module=groupbook&view=index&id=2),

这是因为他把&当成第一个的参数了,简单理解为

http://xxx/login.php?op=logout&return=http://xxx/module.php?module=groupbook&view=index&id=2,

变成了

http://xxx/login.php?op=logout&return=http://xxx/module.php?module=groupbook&view=index&id=2。

这个时候我们需要对当前获取的$_SERVER['REQUEST_URI'] 进行转码使用urlencode($_SERVER['REQUEST_URI'])

就可以解决我们的问题
