Beispiele
Beispiel #1 Get the status of a long running job
The worker in this example has an artificial delay added during processing of the string to be reversed. After each delay it calls GearmanJob::status() which the client then picks up.
<?php
echo "Starting\n";
# Create our client object.
$gmclient= new GearmanClient();
# Add default server (localhost).
$gmclient->addServer();
echo "Sending job\n";
# Send reverse job
do
{
$result = $gmclient->doNormal("reverse", "Hello!");
# Check for various return packets and errors.
switch($gmclient->returnCode())
{
case GEARMAN_WORK_DATA:
break;
case GEARMAN_WORK_STATUS:
# get the current job status
list($numerator, $denominator)= $gmclient->doStatus();
echo "Status: $numerator/$denominator complete\n";
break;
case GEARMAN_WORK_FAIL:
echo "Failed\n";
exit;
case GEARMAN_SUCCESS:
break;
default:
echo "RET: " . $gmclient->returnCode() . "\n";
exit;
}
}
while($gmclient->returnCode() != GEARMAN_SUCCESS);
echo "Success: $result\n";
?>
Das oben gezeigte Beispiel erzeugt eine ähnliche Ausgabe wie:
Starting Sending job Status: 1/6 complete Status: 2/6 complete Status: 3/6 complete Status: 4/6 complete Status: 5/6 complete Status: 6/6 complete Success: !olleH
