How phpMyAdmin got its start

phpMyAdmin was created in September 1998 by IT consultant Tobias Ratschiller as a means to make database management easier. He appreciated a similar project called MySQL-Webadmin, but looked to improve on a few of its shortcomings and features it lacked. Ratschiller was successful in creating a better database management solution, evident by the fact that it was quickly adopted by users. However, Ratschiller had to abandon working on phpMyAdmin in 2000 simply because he didn’t have the time to appropriately attend to it. His last release was made in June of that same year. Not long after, the trio of developers Loic Chapeaux, Marc Delisle and Olivier Muller were able to pick up where Ratschiller left off. Since their first release of phpMyAdmin in August 2001, the work of the three developers has helped phpMyAdmin continue to thrive and pick up steam.

With all the powerful features included within phpMyAdmin, it’s easy to forget that its designed to make it easier to manage your MariaDB and MySQL databases. Here are the ways phpMyAdmin makes it possible to do just that:

• Browse Tables – You can view all tables that have existing records with a click of the browse button. From there you’ll see a comprehensive list of the table’s records.
• Table Structure – Click the button to view a list of the table’s field names, attributes, types, collations and just about anything else you could want to know.
• Add Information – Click the Insert button within your phpMyAdmin install to insert records within your database.
• Search Function – Easily find any information you’re looking for within a specific table.
• Drop – Use this functionality to remove an entire table as well as any records that it contains.
• Remove Data – Similar to the drop button, the Empty button gives you the ability to remove data while still keep the newly empty table.
