What potential benefits can be derived from maintaining version information in PHP classes, and how does it impact code management and documentation?

Maintaining version information in PHP classes can help developers keep track of changes, updates, and improvements made to the code over time. This can aid in code management by allowing for easier identification of when and what changes were made, as well as providing a clear reference point for troubleshooting or reverting to previous versions if needed. Additionally, including version information in PHP classes can improve documentation by providing a history of the class's evolution and making it easier for other developers to understand the purpose and functionality of the code.

class MyClass {
    const VERSION = '1.0.0';
    
    // Class implementation goes here
}
