What are the advantages and disadvantages of using a database versus not using a database for storing content in a PHP application?

When storing content in a PHP application, using a database offers advantages such as easier data management, faster querying, and better scalability. However, it also comes with disadvantages like increased complexity, potential security vulnerabilities, and higher resource usage compared to not using a database.
