我在做一个网页。
把session_id()的值保存在cookie中。
然后在用到的时候从cookie中取出session_id()的值。
重新把session_id()的值放到session_id()函数中。
进而找到这个session里的变量的值。
可是session_id($_COOKIE[name])不能用啊。
怎么办?
回复讨论(解决方案)
session_id($_COOKIE[name])?为什么要这么写?
session_id($_COOKIE[name])?为什么要这么写?
您好。我想是在通过把session放到session_id()函数里载入这个ID进而调用相应的变量$_SESSION[name]
您好楼主,你这边确定$_COOKIE[name]是否有值,还有就是在session_id($_COOKIE[name])的$_COOKIE[name]是否是以“测试”这种字符串形式存在。
session跨域处理?
怎么觉得你这兜了一大圈。直接用$_SESSION['name'] = XXXXX设置,$_SESSION['name']获取不行吗?
php 默认将 sessionid 以 PHPSESSID 的名字保存于 cookie
如果需要自行处理,则 session_id($id) 需要在 session_start() 之前执行
session_start() ;先打开

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.

Dependency injection (DI) significantly improves the testability of PHP code by explicitly transitive dependencies. 1) DI decoupling classes and specific implementations make testing and maintenance more flexible. 2) Among the three types, the constructor injects explicit expression dependencies to keep the state consistent. 3) Use DI containers to manage complex dependencies to improve code quality and development efficiency.

SecLists
SecLists is the ultimate security tester's companion. It is a collection of various types of lists that are frequently used during security assessments, all in one place. SecLists helps make security testing more efficient and productive by conveniently providing all the lists a security tester might need. List types include usernames, passwords, URLs, fuzzing payloads, sensitive data patterns, web shells, and more. The tester can simply pull this repository onto a new test machine and he will have access to every type of list he needs.
