How can PHP developers ensure their code is structured correctly to avoid errors like the ones mentioned in the forum thread?

To ensure their code is structured correctly and avoid errors, PHP developers should follow best practices such as using proper indentation, commenting their code, and breaking down complex tasks into smaller, manageable functions. They should also make use of error handling techniques like try-catch blocks to handle exceptions gracefully.

try {
    // Code that may throw an exception
} catch (Exception $e) {
    // Handle the exception
    echo 'An error occurred: ' . $e->getMessage();
}
