The path to obtain the previous page address is often encountered. You can return to the previous page for use to implement this operation through JS. The following is a good example.

In actual projects, we often encounter the path to get the previous page address. You can return to the previous page to use
The Code is as follows:
Script window. history. go (-1); script
This is operated through JS.
In such a scenario, when the user needs to exit the account, you want him to exit directly on the current page
For example, the current page address is? Module = groupbook & view = index & id = 2.
When you exit the system, you must use $ _ SERVER ['request _ URI '] to obtain the current path, and then pass this value as a parameter to the path to be returned for exit.
He only obtained? Module = groupbook does not get & view = index & id = 2, which means the address returned after we exit is changed
? Module = groupbook (which is supposed to be? Module = groupbook & view = index & id = 2 ),
This is because he regards & as the first parameter, which is simply understood
? Op = logout & return = http: // xxx/module. php? Module = groupbook & view = index & id = 2,
Changed
? Op = logout & return = http: // xxx/module. php? Module = groupbook & view = index & id = 2.
In this case, you need to use urlencode ($ _ SERVER ['request _ URI ']) to transcode the currently obtained $ _ SERVER ['request _ URI'].
We can solve our problem.
