How can the PHP script be modified to handle errors more effectively and provide meaningful feedback to the user?

The PHP script can be modified to handle errors more effectively by using try-catch blocks to catch exceptions and provide meaningful feedback to the user. Within the catch block, specific error messages can be displayed to inform the user about what went wrong.

try {
    // Code that may throw an exception
    $result = 10 / 0;
} catch (Exception $e) {
    // Display a meaningful error message to the user
    echo "An error occurred: " . $e->getMessage();
}
