广州传智播客PHP班首次举行骑车之旅
昨天上午,广州传智播客PHP首期班的同学们在班导杨文婷老师的带领下,愉快地进行了一段官洲骑车之旅。小伙伴们来到久违的大自然,熟悉的泥土味扑面而来让大家顿时“清醒”了不少。就连李东超老师也参加了。郊外的马路,宽广大气,视野开阔,刹那间真有种“两岸猿声啼不住,轻舟已过万重山”的感觉啊~
3月12日,正值植树节之际,万物大地一片春意盎然。传智播客广州PHP培训班的同学们在老师的带领下来到了官洲骑车。天空细雨迷蒙却不足以打湿我们,一路上,同学们欢声笑语。这也是我们首期PHP班首次举行班级活动。
??? 由于这期班的同学比较多,好几个老师加入了我们的队伍,维护同学的秩序和安全。除了班主任杨老师,还是副班主任陈婷老师,吴贤在老师,长期为同学们就业作服务的梁红英老师,还有带我们的李东超老师。他们和同学们一同见证了这次有意义的骑车之旅,也记住这有意义的一天。

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.
