关于set_time_limit（0）的问题？
请问在iis服务器下，php中的set_time_limit（0）为什么没有作用?
------解决方案--------------------
几个原因排查一下：
1. php是否运行在安全模式下，如果是的话，set_time_limit是无效的。

2. IIS服务器本身配置了超时，且优先级更高，即使你 php设置了不超时，由于服务器的超时机制，还是会做超时处理，因此在超时后会触发致命错误，这就是导致500错误的原因。
参考一下这篇文章：http://www.iisadmin.co.uk/?p=7

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

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.

PHP Performance: Identifying and Fixing BottlenecksMay 11, 2025 am 12:13 AM

PHP 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.
