How to be a Good Developer
Article Introduction：Continuous improvement: The secret to becoming an excellent PHP developer
In the ever-changing software development industry, continuous learning and application of new knowledge is a quality that every developer, especially PHP developers, must possess. Successful developers all have one thing in common: they love programming and regard good programming practice as an art form. This article will explore how to improve development skills by following programming “etiquette” and share how this knowledge can be used to guide others to improve themselves.
Core points
A good developer is a professional who is willing to share knowledge, be responsible for his work, be brave to accept criticism and continue to learn and improve.
Writing high-quality code requires reading and understanding source code, learning new technologies, taking time to evaluate problems, testing code, and understanding can help solve problems

php get all dates between two dates
Article Introduction：To get all dates between two dates, it is not difficult to implement with PHP. Just pay attention to the time format and loop logic, and it can be easily done. Generate date list using the DateTime class PHP's built-in DateTime class is a good tool for handling dates. We can use it to iterate through every day between the start date and the end date. functiongetDatesBetween($start,$end){$dates=[];$current=newDateTime($start);$end=newDateTime($end);whi

Spooky Scary PHP
Article Introduction：Have pumpkin candy and cider ready? The annual Halloween is here again! Although the fanaticism around the world is not as good as the United States, I still want to share some "horrible" PHP tips to celebrate this festival. This post is easy and fun and will show you some of the surprising (but logical) behaviors of PHP itself, as well as those creepy (and possibly very illogical) ways some people use PHP to complete tasks. You can think of it as my holiday gift, a little bit of programmer’s “spiritual candy” – after all, why candy only kids who don’t give it all the delicacies?
Summary of key points
PHP may exhibit unexpected behavior, such as retaining references outside the first foreach loop,

PHP Constants: Const vs. Define
Article Introduction：Defining constants in PHP, const is more suitable for constant definitions inside classes, and define() is more flexible and suitable for global or dynamic definitions. 1.const is a language structure, and must be a compile-time constant expression when defined, which is suitable for class or global namespaces; define() is a function, and the value can be the result of runtime calculation. 2.const is affected by the namespace, and the constants defined by define() are visible globally by default. 3. The const structure is clear and the IDE is good, which is suitable for object-oriented design; define() has high flexibility but may have higher maintenance costs. 4. define() supports runtime condition judgment and dynamic definition, but const does not support it. Therefore, class-related constants preferentially use co

What are the differences between Interfaces and Abstract Classes in PHP?
Article Introduction：In PHP, the difference between interfaces and abstract classes is mainly reflected in the definition, inheritance model and implementation method. 1. The interface only defines method signatures (PHP8.1 supports default methods), emphasizing "what should be done", while abstract classes can contain abstract methods and concrete implementations, emphasizing "how to implement some functions". 2. Classes can implement multiple interfaces, but can only inherit one abstract class, so interfaces are more flexible when combining multiple behaviors. 3. The interface method is exposed by default and cannot have attributes. Abstract classes support arbitrary access control, attributes, constructors and destructors. 4. Use interfaces when a unified API is required or when an interchangeable component is designed; use abstract classes when a shared state or logically related classes. The selection basis is: the interface is used to define the contract, and the abstract class is used to share the implementation logic.

Tips for Writing PHP Comments
Article Introduction：The key to writing PHP comments is to clarify the purpose and specifications. Comments should explain "why" rather than "what was done", avoiding redundancy or too simplicity. 1. Use a unified format, such as docblock (/*/) for class and method descriptions to improve readability and tool compatibility; 2. Emphasize the reasons behind the logic, such as why JS jumps need to be output manually; 3. Add an overview description before complex code, describe the process in steps, and help understand the overall idea; 4. Use TODO and FIXME rationally to mark to-do items and problems to facilitate subsequent tracking and collaboration. Good annotations can reduce communication costs and improve code maintenance efficiency.

What are the best practices for writing clean and maintainable PHP code?
Article Introduction：The key to writing clean and easy-to-maintain PHP code lies in clear naming, following standards, reasonable structure, making good use of comments and testability. 1. Use clear variables, functions and class names, such as $userData and calculateTotalPrice(); 2. Follow the PSR-12 standard unified code style; 3. Split the code structure according to responsibilities, and organize it using MVC or Laravel-style catalogs; 4. Avoid noodles-style code and split the logic into small functions with a single responsibility; 5. Add comments at key points and write interface documents to clarify parameters, return values ??and exceptions; 6. Improve testability, adopt dependency injection, reduce global state and static methods. These practices improve code quality, collaboration efficiency and post-maintenance ease.
