Örnek 1 Simple worker making use of extra application context data


# get a gearman worker
$worker= new GearmanWorker();

# add the default server (localhost)

# define a variable to hold application data
$count= 0;

# add the "reverse" function
$worker->addFunction("reverse", "reverse_cb", $count);

# start the worker
while ($worker->work());

reverse_cb($job, &$count)
"$count: " . strrev($job->workload());


Running a client that submits two jobs for the reverse function would have output similar to the following:

1: olleh
2: dlrow
