What are some best practices for updating multiple database records with checkboxes in PHP?

When updating multiple database records with checkboxes in PHP, it is important to loop through each checkbox value to determine which records need to be updated. You can use an array of checkbox values to identify the records that should be updated and then execute an SQL query to update those records accordingly. 

// Assuming form submission with checkboxes named 'record_ids[]'
if(isset($_POST['submit'])){
    $record_ids = $_POST['record_ids'];

    // Connect to database
    $conn = new mysqli('localhost', 'username', 'password', 'database');

    // Loop through each checkbox value
    foreach($record_ids as $id){
        // Update database records based on checkbox values
        $sql = "UPDATE records SET column_name = 'new_value' WHERE id = $id";
        $conn->query($sql);
    }

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