ini_getini_setphp

php中的ini_set函数是php自带的用来修改设置php.ini配置文件的函数,用这个函数很方便,不用去手动修改php.ini文件,有时候我们也没有权限去修改php.ini文件,这时就用这个函数。

语法：ini_set("选项","值");该函数用时最好放到php的脚本最头部

比如：ini_set("max_execution_time", "180");//设置php的脚本超时时间为180秒

具体php选项可参考phpinfo文件的 Configuration PHP Core 部分

ini_get正好和ini_set相反,用来取php.ini文件里的环境变量的值.

语法：string ini_get (string varname );返回选项的值，如果选项的值为布尔型则返回为0或1

比如：echo ini_get('max_execution_time');//输出 30

如果想获取整个php.ini里的变量值,我们可以用ini_get的加强函数 ini_get_all()它以数组的形式返回整个php的环境变量。

Dependency Injection in PHP: Code Examples for BeginnersMay 14, 2025 am 12:08 AM

You should care about DependencyInjection(DI) because it makes your code clearer and easier to maintain. 1) DI makes it more modular by decoupling classes, 2) improves the convenience of testing and code flexibility, 3) Use DI containers to manage complex dependencies, but pay attention to performance impact and circular dependencies, 4) The best practice is to rely on abstract interfaces to achieve loose coupling.

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

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.
