How can checkboxes in a PHP form be used to update corresponding database records?

To update corresponding database records based on checkboxes in a PHP form, you can loop through the checkboxes in the form submission and update the database records accordingly. You can use the checkbox values to identify the records to update and then execute SQL queries to update those records in the database. 

<?php
// Assuming form submission method is POST
if ($_SERVER["REQUEST_METHOD"] == "POST") {
    // Connect to your database
    $conn = new mysqli("localhost", "username", "password", "database");

    // Loop through the checkboxes
    foreach ($_POST['checkbox'] as $checkboxValue) {
        // Use the checkbox value to update corresponding database record
        $sql = "UPDATE your_table SET column_to_update = 'new_value' WHERE id = $checkboxValue";
        $result = $conn->query($sql);
    }

    // Close the database connection
    $conn->close();
}
?>
