CRUD Application means, Create, Read, Update and Delete. In this tutorials. I will explain how to perform CRUD operations using PHP OOPs jquery AJAX with Mysql.
Create Mysql Database Table
In the first step we need to create a database and tables, so here I have created a database of tables “webscodex” and ”customers” with identifiers and columns with names. You simply create a Users table as described in the SQL query.
-- Database: `webscodex` -- Table structure for table `customers` CREATE TABLE `customers` ( `id` int(100) NOT NULL PRIMARY KEY AUTO_INCREAMENT, `name` varchar(100) NOT NULL, `email` varchar(100) NOT NULL, `username` varchar(100) NOT NULL, `dob` date NOT NULL ) ENGINE=InnoDB DEFAULT CHARSET=utf8mb4;
Create Database Class with CRUD method
In this post you will create class for MySQL database connections and CRUD operations, like Select, insert, update and delete with MySQL database.
We’ll have a displayRecord() method for selecting client records, an insertRecord() method for inserting client records, an updateRecord() method for updating client data, and a deleteRecord() method for deleting the client’s Own records. and the getRecordById() method to get a single record.
Here is a complete client class with all their methods. All you have to do is change the MySQL database connection details while it is running on your server.
but in this post we are using PHP OOPs with jQuery AJAX and also use Data-table for show data with pagination and Sweet alert for sweet popup message. CRUD Application with PHP-OOPS Mysql

Call Insert, View, Update, Edit, and Delete Function
Database is a constructor function used for making localhost connections and database selection.
- The public function insertRecord() function has a parameter that accepts input from the HTML form.
- The public function displayRecord() reads all data from the customers table.
- The public function getRecordById() has a user ID parameter. This function reads data based
- on user ID.
- The public function updateRecord() function has some sort of user ID parameter that accepts input from an HTML record update form.
- The public function deleteRecord() function has a rid parameter. Based on the error (line ID),
- this function clears the data.
