From manual page: http://www.php.net/gearmanclient.dobackground

The GearmanClient::do method has been marked as deprecated in favour of using GearmanClient::doNormal. This is understandable and makes the API more readable:

- GearmanClient::doLow
- GearmanClient::doNormal
- GearmanClient::doHigh

However, the same deprecation has not applied to the GearmanClient::doBackground method. Note that GermanClient::do{Low,High}Background methods already exist, so I believe GearmanClient::doNormalBackground should be added to make the API consistent across blocking and background tasks:

- GearmanClient::doLow
- GearmanClient::doNormal
- GearmanClient::doHigh
- GearmanClient::doLowBackground
- GearmanClient::doNormalBackground <- This currently doesn't exist (it's ::doBackground instead)
- GearmanClient::doHighBackground

Test script:
---------------
<?php

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

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

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

Expected result:
----------------
GearmanClient::doNormalBackground works as doBackground currently does.

Actual result:
--------------
Fatal error, doNormalBackground method does not exist
