How can PHP be used to update multiple database records based on user input from radio button groups?

To update multiple database records based on user input from radio button groups, you can use PHP to loop through the selected values and update the corresponding records in the database. You can achieve this by capturing the selected values from the radio button groups in an array and then using a foreach loop to update each record individually. 

// Assuming you have an array of selected values from radio button groups
$selectedValues = $_POST['selected_values'];

// Connect to your database
$pdo = new PDO('mysql:host=localhost;dbname=your_database', 'username', 'password');

// Loop through the selected values and update the database records
foreach ($selectedValues as $value) {
    $stmt = $pdo->prepare("UPDATE your_table SET column_to_update = :value WHERE id = :id");
    $stmt->bindParam(':value', $value);
    $stmt->bindParam(':id', $id); // Assuming you have an ID for each record
    $stmt->execute();
}
