例1 A simple worker with a 5 second timeout

<?php

echo "Starting\n";

# Create our worker object.
$gmworker= new GearmanWorker();

# Add default server (localhost).
$gmworker->addServer();

# Register function "reverse" with the server.
$gmworker->addFunction("reverse", "reverse_fn");

# Set the timeout to 5 seconds
$gmworker->setTimeout(5000);

echo
"Waiting for job...\n";
while(@
$gmworker->work() || $gmworker->returnCode() == GEARMAN_TIMEOUT)
{
if (
$gmworker->returnCode() == GEARMAN_TIMEOUT)
{
# Normally one would want to do something useful here ...
echo "Timeout. Waiting for next job...\n";
continue;
}

if (
$gmworker->returnCode() != GEARMAN_SUCCESS)
{
echo
"return_code: " . $gmworker->returnCode() . "\n";
break;
}
}

echo
"Done\n";

function
reverse_fn($job)
{
return
strrev($job->workload());
}

?>

Running the worker with no submitted jobs will generate output that looks like the following:

Starting
Waiting for job...
Timeout. Waiting for next job...
Timeout. Waiting for next job...
Timeout. Waiting for next job...
