In PHP queue workers, how do I retry transient errors?

In PHP queue workers, handling transient errors effectively is crucial for maintaining a robust application. Transient errors are those that may be temporary and could resolve themselves upon retrying the operation. For example, network issues, temporary service unavailability, or database connection timeouts are common transient errors that can occur during queue processing.

To implement a retry mechanism for transient errors, you may follow the example code below:

performTask(); } catch (TransientErrorException $e) { // Handle transient errors by retrying $this->retryJob(); } } protected function performTask() { // Simulate task processing that may throw a transient error if (random_int(0, 1)) { throw new TransientErrorException('Temporary error occurred!'); } // Continue with normal task processing echo "Task completed successfully."; } protected function retryJob() { // Retry the job for transient errors sleep(5); // Wait before retrying Queue::later(now()->addSeconds(5), new self); } } ?>
