Description:
------------
When assigning a unique identifier by running 
doBackground(name,data,id) it cannot be retrieved at the other 
end in the worker function.





Reproduce code:
---------------
--- worker.php
<?php
  $worker= new GearmanWorker();
  $worker->addServer();
  $worker->addFunction("title", "title_function");
  while ($worker->work());

  function title_function($job)
  {
        var_dump($job->unique());
        return ucwords(strtolower($job->workload()));
  }
--- client.php
<?php
$client = new GearmanClient();
$client->addServers('uslx1');
print $client->doBackground('title', "AlL THE World's a sTagE",'unique');
print "\n";


Expected result:
----------------
string "unique"
job handle

Actual result:
--------------
string(0) ""
job handle

This is not a bug.
You need add the option GEARMAN_WORKER_GRAB_UNIQ to you 
worker options.

<?php
  $worker= new GearmanWorker();
  $worker->addServer();
  $worker->addOptions(GEARMAN_WORKER_GRAB_UNIQ);
  ....
?>

GearmanJob::unique will nor return the unique value the 
client assigns it

Then there is something wrong with the documentation 
(http://www.php.net/manual/en/gearmanjob.unique.php)

"Returns the unique identifiter for this job. The identifier 
is assigned by the client."

Quite the opposite to 
"GearmanJob::unique will nor return the unique value the 
client assigns it"

I just realized that you meant now instead of not. I 
apologize for my hasty conclusion. The option should perhaps 
be mentioned in the documentation then. As the function seems 
not to be working without it. Well then i rest my case, thank 
you for responding.

sorry for the mispelling/grammar, was having a fat fingers 
day. Yes this does need fixing in the documentation. I'll 
raise a bug for it.
