即可解决:
set_time_limit(900);
这个函数指定了当前所在php脚本的最大执行时间,
虽然设定值是900秒,实际上
最大执行时间=php.ini里的max_execution_time数值 - 当前脚本已经执行的时间 + 设定值
假如php.ini里的max_execution_time=30,当前脚本已经执行10秒,则:
最大执行时间=30-10+900=920秒。
经过如此修改后,PHP脚本成功更新200000条记录。
以上是在LAPP环境中通过的。
另外,据说这个方法在windows环境无效,在windows环境需要指定php.ini里的max_execution_time数值。
没有测试这种情况。

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.
