Create, read, update or delete (CRUD) MySQL database records – these are some of the basic things a PHP web programmer must be able to code effortlessly. But if you are a beginner or just want to have a little reference on how these things can be coded, this tutorial post is for you!

This post contains three ways to do this simple PHP CRUD grid. The most updated way is using the PDO extension. MySQLi extension can also be used. And the oldest way is using the MySQL extension.

MySQL extension is not recommended, it has been deprecated since PHP 5.5, so for newer versions of PHP, we have to use either MySQLi (i means improved) or PDO extension. But if you’re debugging with an old software, you can still use this reference I provided below
