pthreads（一）爆线程堆栈

1 脚本

<?php
class demo extends Thread{ // 需pthreads扩展
    public $num = 0;
    public function __construct($num){
        $this->num = $num;
    }

    public function run(){
        echo "$this->num run\n";
        return $this->num;
    }
}

$pool=[];
for($i = 0 ;$i < 10000000 ; $i++){
    $pool[$i] = new demo($i);
    echo "memory: ".memory_get_usage()."\n";
    $pool[$i]->start();
}

2 运行(命令行下)
