我已經有了，它具有以下功能一個cron運行PHP腳本：在cron上運行PHP腳本。日誌輸出不正確
- 過程中的項目隊列
- 如果項目成功處理，processQueueItem（）方法返回true。如果不成功，則返回false。
- 重複在50分鐘
該代碼還包括回聲以將信息輸出到我已經設置了一個日誌while循環。
下面的代碼：
<?php
require_once('/var/www/vhosts/com-ext.com/httpdocs/745_TheYGSGroup/LWC_API/com/MindFireInc/LookWhosClicking/class.LWC.php');
require_once('/var/www/vhosts/com-ext.com/httpdocs/745_TheYGSGroup/LWC_API/com/MindFireInc/Database/class.DB.php');
require_once('/var/www/vhosts/com-ext.com/httpdocs/745_TheYGSGroup/includes/classes.php');
echo date("M d Y H:i:s"), " cron.processQueue.php has started.", "\n";
$consumer = new Consumer;
set_time_limit(3300);
$RUNS_MIN = 10;
$itemCount = 0;
$startedOn = time();
$expireOn = $startedOn + (60 * $RUNS_MIN); // In Sec
while(time() < $expireOn) {
if($consumer->processQueueItem())
$itemCount++;
if($itemCount % 60 == 0)
echo date("M d Y H:i:s"), " Script still running... ", $itemCount, " processed.\n";
}
echo date("M d Y H:i:s"), " cron.processQueue.php has ended. Processed ", $itemCount, " items. \n";

的processQueueItem（）工作正常（這就是爲什麼我不包括在這個崗位腳本）和輸出工作正常，但我對加工物品的計數表現怪異。
如果腳本運行且隊列爲空，它將睡眠（60）併爲processQueueItem（）返回false。它輸出「cron.processQueue.php已經啓動」以及50個「腳本仍在運行... 0已處理」行。最後輸出「已結束」腳本。這裏有一個例子：

但是，如果隊列中有100個項目（隊列以大約1項目中的第二被處理），腳本完成所有項目，給它最後一個「腳本的輸出仍運行...「然後停止。由於此腳本在cron上運行，因此日誌中列出的下一個項目是「cron.processQueue.php已啓動。」這裏有一個例子：
May 31 2012 16:30:01 pullData.php has started.
May 31 2012 16:31:18 Script still running... 60 processed.

我不明白爲什麼它必須經過一些項目，然後有沒有項目，腳本的一個運行中我的過程沒有結束。我真的很抱歉，如果這沒有任何意義，但任何洞察力將不勝感激！
