php开发环境里，安装了xdebug模块后，var_dump()输出的结果将比较易于查看，但默认情况下，var_dump() 输出的结果将有所变化：过多的数组元素不再显示，字符串变量将只显示前N个字符，较深的数组元素也被显示成省略号。这点会带来一些不便，我们修改配置文件，设置这些。

在php.ini里的xdebug节点中，加入如下

xdebug.var_display_max_children=128
xdebug.var_display_max_data=512
xdebug.var_display_max_depth=5

含义从名字上看就可看懂。

然后重启PHP服务即可。

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.
