今天研究了worker stackable的配合方法，写了两种形式，虽然能工作，但是都会出现内存不听增长的问题；

于是把第一个方法的代码邮件给了作者，到现在他没有回复我。

我最后放弃两者配合的方式，直接使用worker，发现到现在执行了582000个工作，内存没有增长，速度也基本稳定，代码如下：

<?php

ini_set('zend.enable_gc', true);

class ExampleWorker extends Worker {

	public $stack_count = 0;

	public function __construct() {}

	public function run(){

		sleep(1);//waiting for data

		$count = 0;

		$data_flag = true;

		$stime = microtime(true);

		while(1){

			if($data = $this->shift()){

				$data_flag = true;

				$this->doSomeWork();

				if((++$count)%1000==0){

					printf("Work Mermory used %.3fMB RAM, time: %3f===> %d \n",

					memory_get_peak_usage(true)/1048576, (microtime(true) - $stime), $count);

					$stime = microtime(true);

				}

			}else{

				usleep(100000);

			}

		}

		exit;

	}

	private function doSomeWork(){

		$str = 'sdalsadkfkasd;lfksa;ldfkas;lkf;lsadkf;as';

		$len = strlen($str);

		$s = substr($str,rand(0,$len));

		$len = floor(strlen($s)/2);

		for($i=0;$i<$len;$i++){

			$tmp = $s[$i];

			$idx = intval($len-$i-1);

			$s[$i] = $s[$idx];

			$s[$idx] = $tmp;

		}

	}

}

$worker= new ExampleWorker(sprintf("Worker [%d]", 0));

$worker->start();

$stime = microtime(true);

$count = 3000000;//99999999;

$total = $count*5;

$ct = 0;

while($count--){

	//for ($target = 0; $target < 5; $target++)

	$worker[]='data_'.(++$ct);

	usleep(rand(200,1800));

}

//sleep(10);

$runtime = (microtime(true)-$stime);

printf("---------------------------------------------------------\n");

printf("Used time is %f \n", $runtime);

printf("Mermory used %.3fMB RAM, added %d, left %d\n", memory_get_peak_usage(true)/1048576, $total, count($worker));

printf("---------------------------------------------------------\n");

//var_dump($works);
