PHP多线程类及用法实例

/**
* @title: PHP多线程类(Thread)
* @version: 1.0
*
* PHP多线程应用示例：
* require_once 'thread.class.php';
* $thread = new thread();
* $thread->addthread('action_log','a');
* $thread->addthread('action_log','b');
* $thread->addthread('action_log','c');
* $thread->runthread();
*
* function action_log($info) {
* $log = 'log/' . microtime() . '.log';
* $txt = $info . "rnrn" . 'Set in ' . Date('h:i:s',time()) . (double)microtime() . "rn";
* $fp = fopen($log,'w');
* fwrite($fp,$txt);
* fclose($fp);
* }
