最近安装了一个liip版PHP,感觉很多函数用起来比原生的更有意思。自己是否可以定制一些内置函数。如果可以,能不能贴个方法呢?谢谢各位大大了。

上面的答案难度略大(需要C)
其实对于PHP程序员,有个纯PHP的解决方案。
在php.ini里有个配置项 auto_prepend_file,可以设置一个PHP文件作为每次执行前自动加载的文件。
在这个文件里写函数,你就可以当成定制的内置函数来用了。
写一个PHP扩展 看这里
任何内置函数需要些C语言的底层扩展的
@chenhengqi 的答案是写php7版本的扩展,php7之前的扩展开发请看这里

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.
