Article Introduction:Key Points
GD and ImageMagick are both popular PHP image processing libraries. GD is more widely used and ImageMagick is more powerful.

How to create a callback function in PHP?
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.

php how to get current year
Article Introduction:Getting the current year can be achieved in PHP through two main methods. 1. Use the date('Y') function to directly output four-digit years, which is suitable for simple scenarios; 2.
