What are best practices for handling errors in PHP classes, considering performance implications?

When handling errors in PHP classes, it is important to use exceptions for error handling rather than relying solely on PHP error functions like die() or trigger_error(). Exceptions provide a more structured way to handle errors and allow for better control over error handling flow. Additionally, it is recommended to use try-catch blocks to catch and handle exceptions gracefully, improving the overall robustness of the code.

class ExampleClass {
    public function doSomething() {
        try {
            // Code that may throw an exception
        } catch (Exception $e) {
            // Handle the exception, log it, or rethrow it
        }
    }
}
