phppthreads多线程扩展的使用：一个较为稳定例子。

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] view plain copy print ?

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);

虚拟上的运行速度：

[plain] view plain copy print ?
