How can error return codes be helpful in troubleshooting Gearman Worker and Client issues in PHP?

Error return codes can be helpful in troubleshooting Gearman Worker and Client issues in PHP by providing specific information about what went wrong during the execution of a job. By checking the return codes, developers can identify the source of the problem and take appropriate actions to resolve it. This can include handling errors gracefully, logging the issue for further investigation, or retrying the job. 

$worker= new GearmanWorker();
$worker->addServer();

$worker->addFunction('reverseString', function($job) {
    $workload = $job->workload();
    
    if(!$workload) {
        return GEARMAN_WORK_FAIL;
    }
    
    $reversedString = strrev($workload);
    
    // Do something with the reversed string
    
    return $reversedString;
});

while ($worker->work());
