GearmanWorker::addFunction — Register and add callback function
Registers a function name with the job server and specifies a callback corresponding to that function. Optionally specify extra application context data to be used when the callback is called and a timeout.
The name of a function to register with the job server
A callback that gets called when a job for the registered function name is submitted
A reference to arbitrary application context data that can be modified by the worker function
An interval of time in seconds
Gibt bei Erfolg TRUE zurück. Im Fehlerfall wird FALSE zurückgegeben.
Beispiel #1 Simple worker making use of extra application context data
<?php
# get a gearman worker
$worker= new GearmanWorker();
# add the default server (localhost)
$worker->addServer();
# define a variable to hold application data
$count= 0;
# add the "reverse" function
$worker->addFunction("reverse", "reverse_cb", &$count);
# start the worker
while ($worker->work());
function reverse_cb($job, $count)
{
$count++;
return "$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
