The Full Stack Web Development - Database & Job Class

This video tutorial guides viewers through setting up a PHP application to connect to a MySQL database using PDO. It covers creating a configuration file for database parameters, building a database class with private properties and methods for querying, binding, and executing SQL statements. The tutorial also demonstrates extending a job class to utilize the database class for fetching job listings and displaying them on a homepage. The video concludes with a preview of adding category filters and creating individual job pages.
