php该如何学呢
php该怎么学呢?
以前一直做.Net
最近公司的php程序员跑路了 于是拉我来擦屁股!
之前对php的理解为0
这个星期2开始接触php 也发了很多水贴!
几天下来感觉php
不是想象中的那么容易上手
里面的变量声明方式很不习惯
比如一个变量声明在a.php里
然后b.php 引用 一下
就直接在b里面就使用a里面声明的变量了 如果不仔细看根本不知道它来自哪里 看的人云里雾里
为什么是这么奇葩的方式呢 难道不能声明要全局变量吗?
目前发现的最不爽的就是个
不得不抱怨
之前的程序员除了源码什么也没留下
没有任何文档 数据库的字段也么有任何注释
太他妈坑爹了啊!!!!!!!!!!!!!!!
------解决方案--------------------
A程序员留下的注释:这段代码只有我和上帝看得懂
LZ接了A程序员的活,写下一段注释: 现在只有上帝能看懂了
------解决方案--------------------
PHP还用学?虽然我PHP很烂,但是我直接用着呢。
------解决方案--------------------
------解决方案--------------------
找个PHP API看一遍就OK了。
------解决方案--------------------
先看语法,在看例子,最好试着自己写些。
有基础的话,慢慢提高难度。
------解决方案--------------------
看别人代码比自己写还难
------解决方案--------------------
我觉得php的语法是最容易理解的
楼主不要急 慢慢看你也会这么觉得
------解决方案--------------------
代码还是小事,前几天碰到个代码,业务逻辑10几20个elseif分支,然后一句注释没有,还是个封装文件,用在很多地方,直接就放着不敢改,所以代码写得再烂还是要记得写注释,做码农要讲良心。
------解决方案--------------------
我的理解就是看别人的代码,然后准备php手册之类的哪一块不会了随时查阅。或者删除了一个一个加看功能。一开始看一下别人写的视频
------解决方案--------------------

JWT is an open standard based on JSON, used to securely transmit information between parties, mainly for identity authentication and information exchange. 1. JWT consists of three parts: Header, Payload and Signature. 2. The working principle of JWT includes three steps: generating JWT, verifying JWT and parsing Payload. 3. When using JWT for authentication in PHP, JWT can be generated and verified, and user role and permission information can be included in advanced usage. 4. Common errors include signature verification failure, token expiration, and payload oversized. Debugging skills include using debugging tools and logging. 5. Performance optimization and best practices include using appropriate signature algorithms, setting validity periods reasonably,
