Session expiration time setting in php_PHP tutorial
After we use the session to save the user's login information, if the user does not choose to click the logout button but chooses to close the browser directly, will the session saved on the server side exist for a long time?
The answer is no! Because SESSION has an expiration time. If the time between the last modification of the session and the current one exceeds a certain value, the session will be cleared!
There is such an option in the php configuration file php.ini:
; After this number of seconds, stored data will be seen as 'garbage' and
; cleaned up by the garbage collection process.
session.gc_maxlifetime = 1440 www.2cto.com
That is to say, if you do not visit the website for more than 24 minutes, the server will destroy your SESSION, and you will be logged out at this time!

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.

PHP Performance: Identifying and Fixing BottlenecksMay 11, 2025 am 12:13 AMPHP performance bottlenecks can be solved through the following steps: 1) Use Xdebug or Blackfire for performance analysis to find out the problem; 2) Optimize database queries and use caches, such as APCu; 3) Use efficient functions such as array_filter to optimize array operations; 4) Configure OPcache for bytecode cache; 5) Optimize the front-end, such as reducing HTTP requests and optimizing pictures; 6) Continuously monitor and optimize performance. Through these methods, the performance of PHP applications can be significantly improved.
