GearmanWorker::setTimeout — 設定 Socket I/O 活動逾時
timeout以毫秒為單位的時間間隔。負值表示無限逾時。
永遠回傳 true。
範例 #1 具有 5 秒逾時的簡單 worker
<?php
echo "開始\n";
# 建立 worker 物件。
$gmworker= new GearmanWorker();
# 加入預設伺服器 (localhost)。
$gmworker->addServer();
# 向伺服器註冊函式 "reverse"。
$gmworker->addFunction("reverse", "reverse_fn");
# 設定逾時為 5 秒
$gmworker->setTimeout(5000);
echo "等待作業...\n";
while(@$gmworker->work() || $gmworker->returnCode() == GEARMAN_TIMEOUT)
{
if ($gmworker->returnCode() == GEARMAN_TIMEOUT)
{
# 通常這裡會執行一些有用的操作 ...
echo "逾時。等待下一個作業...\n";
continue;
}
if ($gmworker->returnCode() != GEARMAN_SUCCESS)
{
echo "return_code: " . $gmworker->returnCode() . "\n";
break;
}
}
echo "完成\n";
function reverse_fn($job)
{
return strrev($job->workload());
}
?>在沒有提交作業的情況下執行 worker 將會產生如下所示的輸出
Starting Waiting for job... Timeout. Waiting for next job... Timeout. Waiting for next job... Timeout. Waiting for next job...
