请问获取cookie和session过期时间的方法是什么
回复讨论(解决方案)
cookie 的过期时间是你指定的
可用 js 计算出剩余时间，php 只能通过附加辅助 cookie 变量简洁获取
session 过期时间为 0，不需要考虑
有没有get之类的方法查看呢？session的过期时间不是0吧，php.ini里面有配置的
是呀，php.ini里有配置
; Lifetime in seconds of cookie or, if 0, until browser is restarted.
; http://php.net/session.cookie-lifetime
session.cookie_lifetime = 0
session.cookie_lifetime = 0的意思是说浏览器关闭session就失效啊
对呀，session 本来就是关闭浏览器就失效呀
但是session本身也是可以设置过期时间的啊，session.gc_maxlifetime = 1440在浏览器不关闭的情况下，连续1440s没操作页面的session也会失效
越讲越远了
session.gc_maxlifetime 表示的是 session 临时文件最小存留时间，而不是过期时间
session.gc_maxlifetime = 1440
是指在最后一次访问的 1440 秒以后，这个 session 临时文件可以删除了（但不一定被删）
如果在一个页面上停留 24 分钟不做任何操作，那么注销他的登录也是不为过的

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

PHP Dependency Injection: Improve Code TestabilityMay 12, 2025 am 12:03 AMDependency 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.

mPDF
mPDF is a PHP library that can generate PDF files from UTF-8 encoded HTML. The original author, Ian Back, wrote mPDF to output PDF files "on the fly" from his website and handle different languages. It is slower than original scripts like HTML2FPDF and produces larger files when using Unicode fonts, but supports CSS styles etc. and has a lot of enhancements. Supports almost all languages, including RTL (Arabic and Hebrew) and CJK (Chinese, Japanese and Korean). Supports nested block-level elements (such as P, DIV),
