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".

GearmanClient::jobStatus
gearman_job_status
(PECL gearman >= 0.5.0)
GearmanClient::jobStatus -- gearman_job_status — Get the status of a background job
Description
Object-oriented style (method):
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!

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.
