swoole创建多进程之间如何通讯？
网友回复
swoole_process->write(string $data) 向进程的管道中写入数据
swoole_process->read(int $buffer_size = 8192) 从进程的管道中读取数据
示例代码如下：
<?php
$serv = new Swoole\Server("0.0.0.0", 9503);
$serv->set(array(
'worker_num' => 2, //worker process num
));
//创建自定义进程
$process = new Swoole\Process(function($process) use ($serv) {
//接受主进程的消息
while($data=$process->read(10)){
echo $data;
}
});
$serv->addProcess($process);
Swoole\Timer::tick(3000, function () use($process) {
//发送给子进程消息
$process->write("12312312\n") ;
});
$serv->on('connect', function ($serv, $fd){
echo "客户端 ".$fd."连接成功 \n";
});
$serv->on('receive', function ($serv, $fd, $reactor_id, $data) {
echo "客户端 ".$fd."发来消息：".$data."\n";
$serv->send($fd, 'Swoole已经介绍到您发送的消息: '.$data);
});
$serv->on('close', function ($serv, $fd) {
echo "客户端 {$fd}关闭连接\n";
});
$serv->start();
