Usually you will not need to create a GearmanJob object. The GearmanJob instance will be passed to a registered function with the job server when GearmanWorker::addFunction is used:<?php// create the worker$worker= new GearmanWorker();// add the default job server (localhost)$worker->addServer('127.0.0.1', 4730);// define a variable to hold application data$count = 0;// add the reverse function$worker->addFunction('reverse', 'my_reverse_function', $count);// start the worker listening for job submissionswhile ($worker->work());function my_reverse_function(GearmanJob $job, &$count){ $count++; return $count . ': ' . strrev($job->workload()) . "\n";}?>
