This tutorial assumes you’ve already logged in to PhpMyAdmin. Now let’s familiarize ourselves with databases and PhpMyAdmin.

Data in a MySQL/MariaDB database is stored in tables. A simple way of thinking about indexes is to imagine an extensive spreadsheet. This type of system is not always conducive to quick searching; that’s where an index becomes essential. If there is no index, then the database engine has to start at row one and browse through all the rows looking for the corresponding values. If this is a small table, then it is no big deal, but in larger tables and applications where there can be tables with millions and even billions of rows, it becomes problematic. As you can imagine, searching through those rows one by one will be time-consuming, even on the latest hardware. The solution is to create an INDEX (or more than one) for your data.

Copying a table is quick and easy to do within PhpMyAdmin. Whether you are trying to make a backup copy before changes are made, archiving data, moving data to a new site or application, or even just working on restructuring your database, PhpMyAdmin can help you get the job done in just a few clicks.
