Explain how garbage collection works in PHP, including reference counting.
Article Introduction：PHP uses reference counting and periodic collector for garbage collection. 1) Reference counting manages memory by tracking the number of references of the object, and frees memory when the count is zero. 2) The periodic recycler processes circular references, detects and releases objects that are no longer referenced externally.

Demystifying PHP's Magic Constants for Context-Aware Applications
Article Introduction：The seven magic constants of PHP are __LINE__, __FILE__, __DIR__, __FUNCTION__, __CLASS__, __TRAIT__, __METHOD__, and they can dynamically return code location and context information, 1. LINE returns the current line number, for precise debugging; 2. FILE returns the absolute path of the current file, often used to reliably introduce files or define root directory; 3. DIR returns the directory where the current file is located, which is clearer and more efficient than dirname (__FILE__); 4. FUNCTION returns the current function name, suitable for function-level log tracking; 5. CLASS returns the current class name (including namespace), in logs and factories

What is the static keyword in C# used for?
Article Introduction：In C#, the static keyword is used to define members belonging to the type itself and can be accessed without instantiation. 1. Static variables are shared by all instances of the class and are suitable for tracking global state, such as recording the number of instantiation of the class; 2. Static methods belong to classes rather than objects, and cannot directly access non-static members, and are often used in helper functions in tool classes; 3. Static classes cannot be instantiated and only contain static members. They are suitable for organizing stateless practical methods, but cannot inherit or implement interfaces. When using it, you need to pay attention to memory management and thread safety issues.

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.
