gearman_job_status

(PECL gearman >= 0.5.0)

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

Description

Object oriented style (method):

public array GearmanClient::jobStatus ( string $job_handle )

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.

Parameters

job_handle

The job handle assigned by the Gearman server

Return Values

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.

Examples

Example #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";

?>

The above example will output something similar to:

 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!
