我做了个ip判断城市进行跳转，放到公共文件就出现不停访问跳转了
我做了个ip判断城市进行二级域名跳转，文件为ipaddress.php，把文件放在公共条用文件里面打开网址就会出现不停访问跳转，现在有什么办法实现这个跳转但不会出现这种无休止访问的问题，我有想到利用cookies，但不知道下来该怎么做，哪位长老帮下忙。
------解决思路----------------------
其实你这段 js 代码是不需要的
你既然是根据用户的 ip 跳转对应的二级域名，那么你就应该有一个城市（地区）与二级域名的对照表
当从 ip 取得城市（地区）名时，从此表查得二级域名进行跳转就可以了（header 函数），当然还要和 $_SERVER['HTTP_HOST'] 比较一下，已经是了就不再跳转了
------解决思路----------------------
地址后面给个标志位比如，transf=1 ，页面首先接受request[""]==1，则不执行判断。
你这样写死了怎么行。。。。
------解决思路----------------------
很简单，主域名 www.xxx.com
分站域名， bj.xxx.com, xa.xxx.com, gz.xxx.com ....

从www来的请求，根据ip跳转到分站，分站的代码不需要跳转，简单判断域名然后用header()跳转就好了。

Dependency Injection in PHP: Code Examples for BeginnersMay 14, 2025 am 12:08 AM

You should care about DependencyInjection(DI) because it makes your code clearer and easier to maintain. 1) DI makes it more modular by decoupling classes, 2) improves the convenience of testing and code flexibility, 3) Use DI containers to manage complex dependencies, but pay attention to performance impact and circular dependencies, 4) The best practice is to rely on abstract interfaces to achieve loose coupling.

Dependency Injection vs. Service Locator in PHPMay 13, 2025 am 12:10 AM

Select DependencyInjection (DI) for large applications, ServiceLocator is suitable for small projects or prototypes. 1) DI improves the testability and modularity of the code through constructor injection. 2) ServiceLocator obtains services through center registration, which is convenient but may lead to an increase in code coupling.
