How can PHP code be optimized to handle multiple mutations in form data without issues?

When handling multiple mutations in form data, one way to optimize PHP code is to use arrays to store the values. This allows for easy iteration and manipulation of the data without needing to create separate variables for each form field. By using arrays, you can efficiently process and validate the form data without cluttering your code with repetitive variable declarations. 

// Example of optimizing PHP code to handle multiple mutations in form data using arrays
$formData = [];

// Store form data in an associative array
foreach ($_POST as $key => $value) {
    $formData[$key] = $value;
}

// Access form data using array keys
$username = $formData['username'];
$email = $formData['email'];

// Perform operations on form data
// Example: sanitize input
$username = filter_var($username, FILTER_SANITIZE_STRING);
$email = filter_var($email, FILTER_SANITIZE_EMAIL);

// Process form data further as needed
