PHP程序员40点陋习

1、不写注释

2、不使用可以提高生产效率的IDE工具

3、不使用版本控制

4、不按照编程规范写代码

5、不使用统一的方法

6、编码前不去思考和计划

7、在执行sql前不执行编码和安全检测

8、不使用测试驱动开发

9、编码时不打开自动报错(error_reporting)

10、不使用一种好的调试工具

11、不重构你的代码(refactor)

12、不采用MVC这样的分层结构

13、不知道以下等等概念:KISS,DRY,MVC,OOP,REST

14、在函数或者类里直接用print或者echo输出东西而不是返回(return)

15、不使用也不去了解单元测试

16、返回HTMl而不是data,strings,objects等类型

17、糟糕的代码和配置参数(hard code messages and configuration parameters)

18、不优化sql查询

19、不使用__autoload

20、不支持自动错误操作(应该是智能纠错)

21、使用$_GET替代$_POST去进行危险的参数传递(记得这40条都是错误的东西)

22、不知道怎样使用正则表达式

23、从未听说过sql注入和跨站脚本(安全方面,应该了解下这两个东西的英文:sql injection,cross-site scripting)

24、不支持简单配置,传递参数给类的构造函数,set/get方法,定义常量

25、不能理解OOP的优缺点

26、无论要做的东西有多小,都使用OOP

27、认为做可复用的软件就是OOP

28、不使用缺省值(don't choose intelligent defaults)

29、不使用单一配置文件

30、不想让别人看到代码,却使用.inc替换掉.php

31、不使用数据库抽象层(持久层)

32、开发时不DRY(Dont repeat yourself). (就是总开发重复的东西)

33、不开发可以重复使用的类或者方法

34、不使用抽象类或者接口类,继承,多态,封装.

35、不使用已有的设计模式优化你的程序.

36、不允许使用者定义基础目录(这点好象PHP不太适合,毕竟不是基于操作系统的开发)

37、错误的使用命名空间,使用大家都普遍使用的单词作为前缀.(这样以后别人使用会造成冲突.,例如自己定义一个function 叫 array_push())

38、使用数据库时不使用表前缀(这个很重要...)

39、不使用或者使用一个陌生的模板引擎(方便团队开发,大家要使用常见的模板)

40、不去看PHP的框架(大多数框架中都包含优秀的代码和先进的概念.值得我们学习)

以下是原文:

1. don't comment your code properly with something like phpDoc

2. don't see the need and/or benefits of a good programming IDE like Zend Studio or Eclipse PDT

3. have never used some form of version control like Subclipse

4. don't adopt some coding & naming standards and general conventions and stick to to them at least throughout the project

5. don't use a consistent methodology

6. don't escape and/or validate properly input or sql queries

7. don't plan your application thoroughly before starting to code

8. don't use test-driven development

9. don't program & test with error reporting on

10. don't see the benefits of a debugger

11. don't refactor your code

12. don't keep the different layers seperated using something like MVC

13. don't know what these stand for: KISS, DRY, MVC, OOP, REST

14. don't return content but echo or print it from your functions or classes

15. have never seen the advantage of unit tests or testing in general

16. return HTML, not data, strings, or objects.

17. hard code messages and configuration parameters

18. don't optimize your sql queries

19. don't use __autoload

20. don't allow intelligent error handling

21. use $_GET instead of $_POST for any destructive actions

22. don't know how to use regular expressions

23. you've never heard of sql injection or cross-site scripting

24. don't allow simple configuration, can be parameters passed to a class’s constructor, set/get methods called later, or constants defined at a runtime.

25. don't understand the benefits and limitations of Object Oriented Programming

26. misuse OOP / everything you write , no matter how small is OOP

27. you think reusable software equals/requires your code to be OOP

28. don't choose intelligent defaults

29. don't have one single configuration file

30. don't want the file contents to be seen, but give it a .inc extension instead of .php

31. don't use a database abstraction layer

32. don't keep it DRY, Don't repeat yourself. If you have to copy and paste or duplicate something your design may be off.

33. don't make a function/class/method do just one thing and don't make them interact.

34. don't try to take advantage of OOP specific features like abstract/interface classes, inheritage polymorphism & access modifiers.

35. don't optimize your application design with established design patterns

36. don't allow your user to define a base directory if you have multiple files and/or directories

37. pollute the global namespace, one option is to prefix the functions in your library with a common string

38. don't allow a table prefix when using database tables

39. use a separate template engine

40. don't take a look at established php frameworks for inspiration, most of them have advanced web dev concepts and good code

Reinhold Weber has put together a list of signs (40 in all on his "programming list of shame") that you're a lousy PHP programmer. Here's a sampling:
don't see the need and/or benefits of a good programming IDE like Zend Studio or Eclipse PDT 
have never used some form of version control like Subclipse 
don't use a consistent methodology 
don't use test-driven development 
don't return content but echo or print it from your functions or classes 
return HTML, not data, strings, or objects. 
don't allow intelligent error handling 
you think reusable software equals/requires your code to be OOP 
Now granted, some of them are a bit more high level than others, but if you're not headed towards a lot of these, you might change paths, hop out of that comfort zone and branch out into the community and the language a little bit more.
