Description: The page ID is a unique identifier assigned to each page in content management systems, used in the database. This integer number allows the system to distinguish between different pages and posts, facilitating content management and retrieval. Each time a new page or post is created, it is automatically assigned an ID that will not be repeated on the same site. This identification system is crucial for the internal functioning of content management systems, as it allows developers and site administrators to perform specific queries in the database, thus optimizing content organization. Additionally, the page ID is often used in permalinks, meaning it can influence the URL structure of a site. Therefore, the page ID is not just a number, but a fundamental element that contributes to the integrity and functionality of the content management system.
