各位大虾好 菜鸟我最近在学 php
是纯粹的年纪比较大?
还是 因为和C语言比较相似?
还是 代码比较轻巧?
回复内容:
简单,容易上手。 高大上的道理我不懂,自己感受PHP最大的好处就是内置的轮子多。我也写过javascript和C、C++,同样一件事php早就写完了,其他语言还在吭哧吭哧写轮子,或者用第三方轮子,这些轮子本身又有各种各样的问题(兼容、冲突、升级……),在轮子上需要花很多精力。
相反PHP多好呢,一大堆各种型号的内置轮子,还有一大堆虽然没内置但可以很容易扩展出来的官方轮子。简直要什么有什么,处理XML,处理json,处理gz,处理字符串,处理各种hash,处理各种编码转换,处理各种格式图片,正则表达式,发送接收邮件,HTTP请求,各种数据库……
虽然php从语言层面被喷得体无完肤,但一俊遮百丑,靠一大堆轮子能快速满足需求也是一个安身立命的本事。 一个神奇的语言,充分发挥编写者的能力。犹如一把玄铁利剑,你强它越强。 开源、简单、成本低、效率高。 主要是完全免费的,当然了,也有好多所谓的优点与缺点,但是事实上是,如果它不是完全免费的,全世界不会有那么多人使用的,虽然,对于中国人来说这不是事,各种收费软件的破解版比比皆是,但对于全球用户,还是喜欢免费而又强大的php。 这个好像罗汉长拳啊,刚学武功的入门功夫。是随着你的功底越深,这个功夫显示出的威力越大。虽说多是平淡无奇的一记直拳差别很大。或者你想象一下魔兽或星际的游戏,入门容易一旦耍深了又是另一片天地 php内置了好多函数,别的语言还要找类库或函数,php很简单,操作文件等一句代码,其他语言要写好多。 简单、易上手,免费开源,同时又有许多很好的开源程序(dz、ecshop、wordpress...)。而且用PHP的人多,很多问题在网上都可以找到很好的解决方案。python、ruby群众基础比不上PHP。 拍黄片 dirty but quick

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.

Dependency injection (DI) significantly improves the testability of PHP code by explicitly transitive dependencies. 1) DI decoupling classes and specific implementations make testing and maintenance more flexible. 2) Among the three types, the constructor injects explicit expression dependencies to keep the state consistent. 3) Use DI containers to manage complex dependencies to improve code quality and development efficiency.
