global $argv;
$startFile = $argv[0];

if(!isset($argv[1])) {
    exit("使用方法: php {$startFile} {start|stop|reload}\n");
}

new Server($argv[1]);

处理task的文件，可以热部署reload.php

<?php

class a{

    public function handle($data){
        echo 'handing';
    }
}

客户端

/**
 * 设置waring等信息
 */
function warning_log($errno, $errstr, $errfile, $errline){
    file_put_contents('error.log',date("Y-m-d H:i:s")."#".$errno."#".$errstr."#".$errfile."#".$errline."\n",FILE_APPEND);
}
set_error_handler("warning_log",E_ALL);
$client = new swoole_client(SWOOLE_SOCK_TCP, SWOOLE_SOCK_SYNC);
if (!$client->connect('127.0.0.1', 9901, 100))
{
    exit("connect failed. Error: {$client->errCode}\n");
}
$client->send("message\r\n");
$client->close();

启动

php server.php start

关闭

php server.php stop

热更新reload.php代码

php server.php reload

ps：

1如果开启opcache请在onWorkerStart中添加,否则会导致热更新失败

opcache_reset();

2. 上述演示代码中reload.php中加载其他的php文件，可以不需要发送reload命令就可以自动更新。
