How can the user improve the error handling in the PHP code to provide more informative messages to the user?

To improve error handling in PHP code and provide more informative messages to the user, you can use try-catch blocks to catch exceptions and display custom error messages. Within the catch block, you can use the getMessage() method to retrieve the specific error message and then display it to the user. 

try {
    // Your PHP code that may throw an exception
} catch (Exception $e) {
    echo "An error occurred: " . $e->getMessage();
}
