First of all, We have to create a table to insert the data using ajax jquery. Here I am using a table named ‘users’ in my database.

DDL information of the table

CREATE TABLE `users` (
`id` int(10) unsigned NOT NULL AUTO_INCREMENT,
`username` varchar(225) COLLATE utf8mb4_unicode_ci DEFAULT NULL,
`phone_no` varchar(100) COLLATE utf8mb4_unicode_ci DEFAULT NULL,
`email` varchar(225) COLLATE utf8mb4_unicode_ci DEFAULT NULL,
`password` varchar(225) COLLATE utf8mb4_unicode_ci DEFAULT NULL,
PRIMARY KEY (`id`)
) ENGINE=InnoDB AUTO_INCREMENT=3 DEFAULT CHARSET=utf8mb4 COLLATE=utf8mb4_unicode_ci
