HomeBackend DevelopmentPHP TutorialPHP程序员的40点陋习_PHP

程序员

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)

How does PHP type hinting work, including scalar types, return types, union types, and nullable types?How does PHP type hinting work, including scalar types, return types, union types, and nullable types?Apr 17, 2025 am 12:25 AM

PHP type prompts to improve code quality and readability. 1) Scalar type tips: Since PHP7.0, basic data types are allowed to be specified in function parameters, such as int, float, etc. 2) Return type prompt: Ensure the consistency of the function return value type. 3) Union type prompt: Since PHP8.0, multiple types are allowed to be specified in function parameters or return values. 4) Nullable type prompt: Allows to include null values ​​and handle functions that may return null values.

How does PHP handle object cloning (clone keyword) and the __clone magic method?How does PHP handle object cloning (clone keyword) and the __clone magic method?Apr 17, 2025 am 12:24 AM

In PHP, use the clone keyword to create a copy of the object and customize the cloning behavior through the \_\_clone magic method. 1. Use the clone keyword to make a shallow copy, cloning the object's properties but not the object's properties. 2. The \_\_clone method can deeply copy nested objects to avoid shallow copying problems. 3. Pay attention to avoid circular references and performance problems in cloning, and optimize cloning operations to improve efficiency.

PHP vs. Python: Use Cases and ApplicationsPHP vs. Python: Use Cases and ApplicationsApr 17, 2025 am 12:23 AM

PHP is suitable for web development and content management systems, and Python is suitable for data science, machine learning and automation scripts. 1.PHP performs well in building fast and scalable websites and applications and is commonly used in CMS such as WordPress. 2. Python has performed outstandingly in the fields of data science and machine learning, with rich libraries such as NumPy and TensorFlow.

Describe different HTTP caching headers (e.g., Cache-Control, ETag, Last-Modified).Describe different HTTP caching headers (e.g., Cache-Control, ETag, Last-Modified).Apr 17, 2025 am 12:22 AM

Key players in HTTP cache headers include Cache-Control, ETag, and Last-Modified. 1.Cache-Control is used to control caching policies. Example: Cache-Control:max-age=3600,public. 2. ETag verifies resource changes through unique identifiers, example: ETag: "686897696a7c876b7e". 3.Last-Modified indicates the resource's last modification time, example: Last-Modified:Wed,21Oct201507:28:00GMT.

Explain secure password hashing in PHP (e.g., password_hash, password_verify). Why not use MD5 or SHA1?Explain secure password hashing in PHP (e.g., password_hash, password_verify). Why not use MD5 or SHA1?Apr 17, 2025 am 12:06 AM

In PHP, password_hash and password_verify functions should be used to implement secure password hashing, and MD5 or SHA1 should not be used. 1) password_hash generates a hash containing salt values ​​to enhance security. 2) Password_verify verify password and ensure security by comparing hash values. 3) MD5 and SHA1 are vulnerable and lack salt values, and are not suitable for modern password security.

PHP: An Introduction to the Server-Side Scripting LanguagePHP: An Introduction to the Server-Side Scripting LanguageApr 16, 2025 am 12:18 AM

PHP is a server-side scripting language used for dynamic web development and server-side applications. 1.PHP is an interpreted language that does not require compilation and is suitable for rapid development. 2. PHP code is embedded in HTML, making it easy to develop web pages. 3. PHP processes server-side logic, generates HTML output, and supports user interaction and data processing. 4. PHP can interact with the database, process form submission, and execute server-side tasks.

PHP and the Web: Exploring its Long-Term ImpactPHP and the Web: Exploring its Long-Term ImpactApr 16, 2025 am 12:17 AM

PHP has shaped the network over the past few decades and will continue to play an important role in web development. 1) PHP originated in 1994 and has become the first choice for developers due to its ease of use and seamless integration with MySQL. 2) Its core functions include generating dynamic content and integrating with the database, allowing the website to be updated in real time and displayed in personalized manner. 3) The wide application and ecosystem of PHP have driven its long-term impact, but it also faces version updates and security challenges. 4) Performance improvements in recent years, such as the release of PHP7, enable it to compete with modern languages. 5) In the future, PHP needs to deal with new challenges such as containerization and microservices, but its flexibility and active community make it adaptable.

Why Use PHP? Advantages and Benefits ExplainedWhy Use PHP? Advantages and Benefits ExplainedApr 16, 2025 am 12:16 AM

The core benefits of PHP include ease of learning, strong web development support, rich libraries and frameworks, high performance and scalability, cross-platform compatibility, and cost-effectiveness. 1) Easy to learn and use, suitable for beginners; 2) Good integration with web servers and supports multiple databases; 3) Have powerful frameworks such as Laravel; 4) High performance can be achieved through optimization; 5) Support multiple operating systems; 6) Open source to reduce development costs.
