Delete Data From MySQL Using PHP 7

To update data that already exist in the database, the UPDATE statement is used.

In the below example we update the employee data from MySQL database.

we used 2 files for update data

database.php- To connecting database.
update.php- TO retrieve data from a database with an update option.
update-process.php- TO update data from the database.

1. database

CREATE TABLE `employee` (
 `userid` int(8) NOT NULL,
 `first_name` varchar(55) NOT NULL,
 `last_name` varchar(55) NOT NULL,
 `city_name` varchar(55) NOT NULL,
 `email` varchar(50) NOT NULL
) ENGINE=InnoDB DEFAULT CHARSET=latin1;

2. database.php

<?php
    $servername =   'localhost';
    $username   =   'root';
    $password   =   '';
    $dbname     =   "db_php_test";
    $conn=mysqli_connect($servername,$username,$password,

                    "$dbname");
if(!$conn)
{
   die('Could not Connect My Sql:' .mysql_error());
}
?>

3. Insert.php

<?php
    include_once 'process.php';
?>
