What is the correct implementation of a WordPress plugin using the singleton pattern with proper hook isolation?

Accepted Answer

The correct implementation involves creating a main plugin class with a private constructor, a static getInstance() method, and hook registration in an init() method to prevent multiple registrations and global variables. This ensures proper hook isolation and a single instance of the plugin.
