What are some best practices for maintaining clean and efficient PHP code in a CMS like Typo3?

One best practice for maintaining clean and efficient PHP code in Typo3 is to follow the PSR-1 and PSR-2 coding standards. This includes using consistent naming conventions, proper indentation, and clear documentation. Additionally, breaking up large functions into smaller, more manageable chunks can improve readability and maintainability.

// Example of following PSR-1 and PSR-2 coding standards
namespace Vendor\Package;

class ClassName
{
    public function methodName($parameter1, $parameter2)
    {
        // code here
    }
}
