Single Page CRUD with Php, MySql, validate.js and Ajax-Post

In this exercise, we will see an illustration program to figure out how to do database CRUD operations utilizing PHP and MySQL with Ajax-Post. CRUD represented as Create, Read, Update and Delete operations with database table records.

In this post, we will go to handle the data values into a database as well as view page with the help of front-end validations like required details using validate.js. We have users table containing users data like full name, username, password, and etc. Using this users table, we need to perform CRUD utilizing MySQL with Ajax-Post.
