How can PHP be used to store the updated values from JavaScript interactions in a database?

When updating values in a database based on JavaScript interactions, you can use AJAX to send the updated data to a PHP script. The PHP script will then process the data and update the database accordingly. This can be achieved by creating an AJAX request in JavaScript that sends the updated values to a PHP script using POST or GET methods. 

<?php
// Get the updated values from the AJAX request
$updatedValue1 = $_POST['updatedValue1'];
$updatedValue2 = $_POST['updatedValue2'];

// Connect to the database
$servername = "localhost";
$username = "username";
$password = "password";
$dbname = "database";

$conn = new mysqli($servername, $username, $password, $dbname);

// Check connection
if ($conn->connect_error) {
    die("Connection failed: " . $conn->connect_error);
}

// Update the database with the new values
$sql = "UPDATE table_name SET column1 = '$updatedValue1', column2 = '$updatedValue2' WHERE condition";

if ($conn->query($sql) === TRUE) {
    echo "Record updated successfully";
} else {
    echo "Error updating record: " . $conn->error;
}

$conn->close();
?>
