What are the best practices for handling error codes in PHP?

When handling error codes in PHP, it is important to properly handle exceptions and errors to provide meaningful feedback to users and developers. Best practices include using try-catch blocks to catch exceptions, logging errors for debugging purposes, and displaying user-friendly error messages.

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