GearmanClient::doStatus — Get the status for the running task

说明

public GearmanClient::doStatus ( void ) : array

Returns the status for the running task. This should be used between repeated GearmanClient::doNormal() calls.

参数

此函数没有参数。

返回值

An array representing the percentage completion given as a fraction, with the first element the numerator and the second element the denomintor.

范例

Example #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.

<?php

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";

?>

以上例程的输出类似于：

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
