Decorators

Decorators are special functions that allow you to modify or extend the functionality of other functions or methods without making changes to their source code. This is an illustration of the "Decorator" pattern in programming.

Application of decorators:

• Changing the behavior of functions: For example, keeping logs, validating data, caching results.
• Code optimization: Removing repetitive pieces of code, such as exception handling or measuring execution time.
• Improving code readability: Instead of duplicating code in several functions, the same logic can be exported to the decorator.

The above is the detailed content of Decorators. For more information, please follow other related articles on the PHP Chinese website!
