I am proficient in mysql database queries. I would like to write a "report writer" that allows users (not programmers) on a particular site to connect to a particular mysql database, select from drop-down menus populated by columns/rows in the database (e.g. student name or sports team) and have a report generated on the web site and available as a PDF printout. I am confused as to where to start....PHP, PHP PDO, JavaScript, JQuery....? I get started and solve one aspect of the challenge but don't seem able to put together a complete plan. Can someone please advise me how to start( re-start).
