- A Comprehensive Guide to Constant Naming Conventions and Best Practices
- Constant naming should be underlined with capital letters (SNAKE_CASE), 1. Use SNAKE_CASE nomenclature, such as MAX_RETRIES=3; 2. Naming should be specific and descriptive, such as HTTP_STATUS_NOT_FOUND=404; 3. Group relevant constants through enums or namespaces, such as Python's Enum class; 4. Avoid magic numbers and strings, and replace hard-coded values with named constants; 5. Use prefixes or suffixes to enhance clarity, such as API_BASE_URL; 6. Follow language-specific specifications, such as UPPER_CASE for Java, and PascalCase for C#; 7. Do not over-constantize, only configure values

- From if-else Chains to the match Expression: A PHP 8 Migration Guide
- Using PHP8 match expressions to replace long if-else chains can improve code security and readability; 1. Ensure that conditions are based on a single variable and strictly compared; 2. Convert each branch to match syntax, pay attention to type consistency; 3. Handle types mismatch problems such as strings and integers; 4. Multi-value merging branches can be used in PHP8.1; 5. The match(true) mode can be used for complex logic; but if-else should be retained when the logic is complex, involving non-scalar values or requires loose comparisons; when migration, it should start with small state mapping, and cooperate with testing and static analysis tools to ensure that all situations are covered, and ultimately achieve a more concise and reliable code structure.

- Advanced PHP Type Casting and Coercion Techniques
- Use declare(strict_types=1) to ensure strict type checks of function parameters and return values, avoiding errors caused by implicit type conversion; 2. Casting between arrays and objects is suitable for simple scenarios, but does not support complete mapping of methods or private attributes; 3. Settype() directly modifyes the variable type at runtime, suitable for dynamic type processing, and gettype() is used to obtain type names; 4. Predictable type conversion should be achieved by manually writing type-safe auxiliary functions (such as toInt) to avoid unexpected behaviors such as partial resolution; 5. PHP8 union types will not automatically perform type conversion between members and need to be explicitly processed within the function; 6. Constructor attribute improvement should be combined with str
