GearmanClient::jobStatus -- gearman_job_status — Get the status of a background job
オブジェクト指向型 (method):
$job_handle
) : arrayGets 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.
job_handleGearman サーバーが割り当てたジョブハンドル。
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!
