What are some best practices for handling error messages in PHP classes and methods?

When handling error messages in PHP classes and methods, it is important to use exceptions to handle errors in a structured and predictable way. By throwing exceptions with descriptive error messages, you can easily identify and troubleshoot issues in your code. Additionally, catching exceptions at the appropriate level allows for graceful error handling and recovery. 

class ExampleClass {
    public function exampleMethod($value) {
        if (!is_numeric($value)) {
            throw new InvalidArgumentException('Value must be numeric');
        }
        
        // Proceed with the method logic
    }
}

try {
    $example = new ExampleClass();
    $example->exampleMethod('abc');
} catch (InvalidArgumentException $e) {
    echo 'Error: ' . $e->getMessage();
}
