What steps can be taken to ensure proper error handling and messaging in PHP scripts for better user experience?

Proper error handling and messaging in PHP scripts can be ensured by using try-catch blocks to catch exceptions and displaying meaningful error messages to the users. By utilizing functions like `trigger_error()` or `error_log()`, developers can log errors for debugging purposes. Additionally, custom error handling functions can be created to handle different types of errors gracefully. 

try {
    // Code that may throw an exception
    throw new Exception("An error occurred.");
} catch (Exception $e) {
    // Display a user-friendly error message
    echo "Sorry, an error occurred. Please try again later.";
    // Log the error for debugging purposes
    error_log("Error: " . $e->getMessage());
}
