How can the PHP code be optimized to improve error handling and user feedback when dealing with account balances and updates?

To improve error handling and user feedback when dealing with account balances and updates in PHP, you can use try-catch blocks to catch exceptions and provide meaningful error messages to the user. Additionally, you can validate input data to ensure it meets the required criteria before processing account updates. 

try {
    // Validate input data
    if (!isset($_POST['amount']) || !is_numeric($_POST['amount'])) {
        throw new Exception('Invalid amount provided.');
    }

    // Process account update
    $newBalance = $currentBalance + $_POST['amount'];

    // Update database with new balance
    // Code to update database goes here

    echo "Account balance updated successfully. New balance: $newBalance";
} catch (Exception $e) {
    echo "An error occurred: " . $e->getMessage();
}
