源码安装PHP完成后,在安装目录中是没有php.ini文件的,需要手动把源代码根目录下的php.ini-development或php.ini-production文件复制到安装目录的lib目录中(或者其他希望的目录中)并重命名为php.ini。
如果php.ini文件修改后不生效,大部分都是因为没有找对php.ini文件,可以使用如下方法来查看php.ini文件的位置:
1、新建PHP文件,写入如下代码:
<?php echo phpinfo();
然后再浏览器访问该页面,搜索php.ini。
2、在命令行中执行如下命令即可查看php.ini文件位置:
#注意使用自己的PHP路径 /user/local/php/bin/php --ini
php.ini文件默认放在PHP安装目录下的lib目录中,可以在编译时使用--with-config-file-path参数来修改php.ini的存放位置。

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.

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.
