GearmanClient::jobStatus -- gearman_job_statusGet the status of a background job

説明

オブジェクト指向型 (method):

public GearmanClient::jobStatus ( string $job_handle ) : array

Gets the status for a background job given a job handle. The status information will specify whether the job is known, whether the job is currently running, and the percentage completion.

パラメータ

job_handle

Gearman サーバーが割り当てたジョブハンドル。

返り値

An array containing status information for the job corresponding to the supplied job handle. The first array element is a boolean indicating whether the job is even known, the second is a boolean indicating whether the job is still running, and the third and fourth elements correspond to the numerator and denominator of the fractional completion percentage, respectively.

例1 Monitor the status of a long running background job

<?php

/* create our object */
$gmclient= new GearmanClient();

/* add the default server */
$gmclient->addServer();

/* run reverse client */
$job_handle $gmclient->doBackground("reverse""this is a test");

if (
$gmclient->returnCode() != GEARMAN_SUCCESS)
{
  echo 
"bad return code\n";
  exit;
}

$done false;
do
{
   
sleep(3);
   
$stat $gmclient->jobStatus($job_handle);
   if (!
$stat[0]) // the job is known so it is not done
      
$done true;
   echo 
"Running: " . ($stat[1] ? "true" "false") . ", numerator: " $stat[2] . ", denomintor: " $stat[3] . "\n";
}
while(!
$done);

echo 
"done!\n";

?>

上の例の出力は、 たとえば以下のようになります。

Running: true, numerator: 3, denomintor: 14
Running: true, numerator: 6, denomintor: 14
Running: true, numerator: 9, denomintor: 14
Running: true, numerator: 12, denomintor: 14
Running: false, numerator: 0, denomintor: 0
done!

The example above reads:
if (!$stat[0]) // the job is known so it is not done

I think the comment is wrong, it should read "the job is unknown, so it is done".

if (!$stat[0]) // the job is known so it is not done

I believe to be correct. I read it as, if $stat[0] returns anything but false, the job is currently running, so we are not done. However, if we cannot find $stat[0] (ie: the job handle no longer exists) then the job is done.
