各位前辈,请教一个问题,很烦恼啊
我是新手,很多东西都不太知道该怎么说好,粗略说一下,希望各位前辈指点指点,谢谢。
一个项目由很多代码组成,但是这些代码也分为很多个文件
例如: 查询数据库使用 view.php
插入数据库 insert.php
更新数据库数据 update_db.php
。。。。。。
一大堆文件,而且代码量也很多,假如每一条代码都看得懂,但是依然觉得越来越乱,这是什么原因?是哪里学得不好?就书上比较大比较多代码的项目,看起来都感觉这样,叫我如何看得懂别人的项目??
回复讨论(解决方案)
首先看命名,除非遇到命名很怪的程序,一般都知道这个function或这个class大概是实现什么功能的。
然后看注释,如果有,这样能够进一步了解程序块的功能。
先区分每个程序块是做什么的,再去想了解的程序块细看。
例如有一个会员系统,你只想了解登入的部分,那不应该去找回密码的部分去看。看别人的代码也是如此。
我最近拿到的系统就1W多文件,除去缓存图片什么的,还是很多,练目录结构都没有。挑重要的看,一半index看起。建议边看边做笔记。第一遍可以很快。你弄懂这个文件大体是做什么的。

只弄懂了大体就好了吗??
基础很重要,多看看文档
刚从新手打怪升级到半新手了...
我个人觉得看别人代码主要看架构和设计模式,具体到某个功能,直接找搜索引擎问原理,然后尝试自己实现
从功能模块开始看起,你想先了解哪就从哪看起,首先要了解他要做什么,当你了解他要做什么了你自我感觉是否可以完成,如果你可以完成OK先别看了,看别地方,当有不明白的地方一定要弄明白,否则你都没有勇气去更改代码,怕出错。
大道至简。心态为上。脚踏泥地。春上枝头。坐火车能看见沿途的风景。坐飞机能欣赏云端的色彩
一大堆文件(你有了一大堆宝藏),而且代码量也很多(其中可能有会垃圾代码,不必烦心),假如每一条代码都看得懂(假如有点自欺欺人。不如先看懂一条代码来的实在),但是依然觉得越来越乱(手里无粮。肚子慌慌。多充实下自己),这是什么原因(相信你会成功的)
