提供了一个基于写入“PID文件”的UNIX进程ID的简单锁定机制。

http://github.com/liip/LiipProcessManager.git

以下是一个简单示例

<?php
use Liip\ProcessManager\ProcessManager;
use Liip\ProcessManager\PidFile;

// run a process in the back ground
$processManager = new ProcessManager();
$pid = $processManager->execProcess('sleep 10m');
$processManager->isProcessRunning($pid)
$processManager->killProcess($pid);

// to set log location instead of routing it to /dev/null by default
$processManager = new ProcessManager('/path/to/logfile');
$pid = $processManager->execProcess('sleep 10m');

// acquire a lock via a pid file
$lock = new PidFile(new ProcessManager(), '/tmp/foobar');
$lock->acquireLock();
$pid = $lock->execProcess('sleep 10m');
// set the PID which should be locked on
$lock->setPid(getmypid());
$lock->releaseLock();
