How can the use of variable variables in PHP be leveraged to dynamically update and pass data between database records when processing form submissions?

When processing form submissions in PHP, variable variables can be used to dynamically update and pass data between database records. By using variable variables, you can easily map form fields to database columns and update records accordingly without hardcoding each field. This allows for more flexibility and scalability in handling form submissions. 

// Assume $formData is an array containing form field names as keys and their corresponding values
// Assume $dbConnection is the connection to your database

// Loop through the form data and update database records dynamically
foreach ($formData as $field => $value) {
    // Use variable variables to dynamically update database records
    $query = "UPDATE table_name SET $field = '$value' WHERE id = $recordId";
    
    // Execute the query
    $result = mysqli_query($dbConnection, $query);
    
    if (!$result) {
        // Handle error
    }
}
