PHP客户端禁用cookie如何使用session
第一种方式:在每个超链接上添加一个PHPSESSID=$sid
//防止返回初始页产生新的session
if(isset($_GET["PHPSESSID"])){
session_id($_GET["PHPSESSID"]);
}
//启动一个session
session_start();
//获取当前session的session_id()
$sid=session_id();
//在每个链接上添加参数PHPSESSID=$sid
其他页面的获取方式为:
if(isset($_GET["PHPSESSID"])){
//设置当前的session为初始的session,session_id()一致即可
session_id($_GET["PHPSESSID"])
}
session_start();
第二种方式:使用 SID 常量替换链接上的 PHPSESSID=$sid (SID的值类似:PHPSESSID=sddg34r593dfdlksrewr)
if(isset($_GET["PHPSESSID"])){
session_id($_GET["PHPSESSID"]);
}
//启动一个session
session_start();
其他页面的获取方式为:
if(isset($_GET["PHPSESSID"])){
//设置当前的session为初始的session,session_id()一致即可
session_id($_GET["PHPSESSID"])
}
session_start();
第三种方式:使用session.use_trans_sid=1,php.ini中配置
这种方式会在url上自动加上SID(href,location,action,注意:js跳转不会添加上SID)

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.

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.
