How can code folding improve the readability and organization of lengthy code blocks in PHP tutorials?

Code folding can improve the readability and organization of lengthy code blocks in PHP tutorials by allowing developers to collapse sections of code that are not currently being worked on. This helps to reduce visual clutter and focus on the relevant parts of the code. To implement code folding in PHP, developers can use code editors or IDEs that support this feature, such as Visual Studio Code or PhpStorm.
