swoole的task以及线程使用案例

<?php
$workers = [];
$worker_num = 2;
for( $i = 1; $i <= $worker_num; $i++){
	$process = new swoole_process('doProcess',false,false);
	$process->useQueue();//开启队列，类似全局函数
	$pid = $process->start();
	$worders[$pid] = $process;
}
function doProcess(swoole_process $process){
	$recv = $process->pop();
	echo "get data from master process is $recv 
";
	sleep(5);
	$process->exit(0);
}
foreach($worders as $pid=>$process){
	$process->push("hello son process $pid");
}
for($i = 1;$i <= $worker_num; $i++){
	$ret = swoole_process::wait();
	$pid = $ret['pid'];
	unset($workers[$pid]);
	echo "son process $pid is out 
";
}

 task使用案例

<?php
$serv = new swoole_server("192.168.50.66",9501);
$serv->set([
	'task_worker_num'	=> 4
]);
$serv->on('receive',function($serv,$fd,$from_id,$data){
		$task_id = $serv->task($data);
		echo "ID：$task_id
";
});
$serv->on('task',function($serv,$task_id,$from_id,$data){
		echo "do ID:$task_id
";
		$serv->finish("$data -> ok");
});

$serv->on('finish',function($serv,$task_id,$data){
	echo "do ok
";
});
$serv->start();

process以及task利用定时器进行动态加载进程池(稍难)

<?php
class BaseProcess
{
	private $process;
	private $process_list = [];
	private $process_use = [];
	private $worker_min_num = 3;
	private $worker_max_num = 6;
	private $current_num;
	public function __construct()
	{
		$this->process = new swoole_process([$this,'run'],false,2);
		$this->process->start();
		swoole_process::wait();
	}
	public function run()
	{
		$this->current_num = $this->worker_min_num;
		for( $i = 0; $i < $this->current_num; $i++){
			$process = new swoole_process([$this,'task_run'],false,2);
			$pid = $process->start();
			$this->process_list[$pid] = $process;
			$this->process_use[$pid] = 0;
		}
		foreach($this->process_list as $pid=>$process){
			swoole_event_add($process->pipe,function($pipe) use($process){
				$data = $process->read();
				var_dump($data);
				$process_use[$data] = 0;
			});
		}
		//核心部分start
		swoole_timer_tick(1000,function($time_id){
			static $index = 0;
			$index = $index + 1;
			$flag = true;
			foreach($this->process_use as $pid=>$used){
				if($used == 0){
					$flag = false;
					$this->process_use[$pid] = 1;
					$this->process_list[$pid]->write($index . ':hello');
					break;
				}
			}
			if($flag = true && $this->current_num <$this->worker_max_num){
				$process = new swoole_process([$this,'task_run'],false,2);
				$pid = $process->start();
				$this->process_list[$pid] = $process;
				$this->process_use[$pid] = 1;
				$this->process_list[$pid]->write($index . ":hello");
				$this->current_num ++;
			}
			if( $index = 10){
				foreach($this->process_list as $process){
					$process->write('exit');
				}
				swoole_timer_clear($time_id);
				$this->process->exit();
			}
			
		});
		//核心部分end
	}
	public function task_run($worker)
	{	
		swoole_event_add($worker->pipe,function($pipe) use ($worker){
			$data = $worker->read();
			var_dump($worker->pid.":".$data);
			if($data =='exit'){
				$worker->exit();
				exit;
			}
			sleep(5);
			$worker->write(''.$worker->pid);

		});
	}
}
new BaseProcess();
