サンプル

例1 Get the status of a long running job
  The worker in this example has an artificial delay added during processing of the string to be reversed. After each delay it calls GearmanJob::status() which the client then picks up.  


echo "Starting\n";

# Create our client object.
$gmclient= new GearmanClient();

# Add default server (localhost).
$gmclient->addServer();

echo "Sending job\n";

# Send reverse job
do
{
  $result = $gmclient->doNormal("reverse", "Hello!");

  # Check for various return packets and errors.
  switch($gmclient->returnCode())
  {
    case GEARMAN_WORK_DATA:
      break;
    case GEARMAN_WORK_STATUS:
      # get the current job status
      list($numerator, $denominator)= $gmclient->doStatus();
      echo "Status: $numerator/$denominator complete\n";
      break;
    case GEARMAN_WORK_FAIL:
      echo "Failed\n";
      exit;
    case GEARMAN_SUCCESS:
      break;
    default:
      echo "RET: " . $gmclient->returnCode() . "\n";
      exit;
  }
}
while($gmclient->returnCode() != GEARMAN_SUCCESS);

echo "Success: $result\n";


 上の例の出力は、たとえば以下のようになります。 
Starting
Sending job
Status: 1/6 complete
Status: 2/6 complete
Status: 3/6 complete
Status: 4/6 complete
Status: 5/6 complete
Status: 6/6 complete
Success: !olleH
