例
例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
