Article Introduction：There are three main ways to create callback functions in PHP, namely, using ordinary functions, anonymous functions and class methods. A callback function is a function passed as a parameter to another function, and is often used in scenarios such as array processing, event-driven programming, and asynchronous processing. 1. When using ordinary functions, you need to pass the function name as a string, such as 'multiply_by_two'; 2. Using anonymous functions (Closure) can make the code more concise and suitable for one-time use; 3. When using class methods, the static method is passed through ['ClassName','method'], and the instance method is passed through objects. It is recommended to choose the appropriate method according to the logical complexity and pay attention to access permissions and code maintainability.
