GearmanWorker::addFunction — Register and add callback function
$function_name
,$function
,$context
= null
,$timeout
= 0Registers 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.
function_name
The name of a function to register with the job server
function
A callback that gets called when a job for the registered function name is submitted
context
A reference to arbitrary application context data that can be modified by the worker function
timeout
An interval of time in seconds
Örnek 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
