客戶端的範例是無效的。由於 doNormal 方法是同步的，因此進度不會顯示在客戶端。
程式碼將只會在 doNormal 完成後執行。
<?php
case GEARMAN_WORK_STATUS:
list($numerator, $denominator)= $gmclient->doStatus();
echo "狀態： $numerator/$denominator 已完成\n";
break;
?>
範例 #1 基本的 Gearman 客戶端和工作程式
此範例顯示了一個非常簡單的客戶端和工作程式。客戶端將字串傳送到作業伺服器，而工作程式則反轉字串並將其傳回。作業同步執行。
<?php
# 建立客戶端物件
$gmclient= new GearmanClient();
# 加入預設伺服器 (localhost)
$gmclient->addServer();
echo "正在送出工作\n";
# 送出反轉工作
do
{
$result = $gmclient->doNormal("reverse", "Hello!");
# 檢查各種回傳封包和錯誤
switch($gmclient->returnCode())
{
case GEARMAN_WORK_DATA:
echo "資料: $result\n";
break;
case GEARMAN_WORK_STATUS:
list($numerator, $denominator)= $gmclient->doStatus();
echo "狀態: $numerator/$denominator 已完成\n";
break;
case GEARMAN_WORK_FAIL:
echo "失敗\n";
exit;
case GEARMAN_SUCCESS:
echo "成功: $result\n";
break;
default:
echo "回傳值: " . $gmclient->returnCode() . "\n";
exit;
}
}
while($gmclient->returnCode() != GEARMAN_SUCCESS);
?><?php
echo "Starting\n";
# Create our worker object.
$gmworker= new GearmanWorker();
# Add default server (localhost).
$gmworker->addServer();
# Register function "reverse" with the server. Change the worker function to
# "reverse_fn_fast" for a faster worker with no output.
$gmworker->addFunction("reverse", "reverse_fn");
print "Waiting for job...\n";
while($gmworker->work())
{
if ($gmworker->returnCode() != GEARMAN_SUCCESS)
{
echo "return_code: " . $gmworker->returnCode() . "\n";
break;
}
}
function reverse_fn($job)
{
echo "Received job: " . $job->handle() . "\n";
$workload = $job->workload();
$workload_size = $job->workloadSize();
echo "Workload: $workload ($workload_size)\n";
# This status loop is not needed, just showing how it works
for ($x= 0; $x < $workload_size; $x++)
{
echo "Sending status: " . ($x + 1) . "/$workload_size complete\n";
$job->sendStatus($x, $workload_size);
sleep(1);
}
$result= strrev($workload);
echo "Result: $result\n";
# Return what we want to send back to the client.
return $result;
}
# A much simpler and less verbose version of the above function would be:
function reverse_fn_fast($job)
{
return strrev($job->workload());
}
?>上述範例會輸出類似以下的內容
% php reverse_worker.php Starting Waiting for job... Received job: H:foo.local:36 Workload: Hello! (6) Sending status: 1/6 complete Sending status: 2/6 complete Sending status: 3/6 complete Sending status: 4/6 complete Sending status: 5/6 complete Sending status: 6/6 complete Result: !olleH
% php reverse_client.php 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
