直接上代码：+?php$http=new swoole_http_server(0.0.0.0, 9501);$http->on('request', function($request, $response) { $swoole_mysql1=new Swoole\Coroutine\MySQL(); $swoole_mysql2=new Swoole\Coroutine\MySQL(); $swoole_mysql1->connect(...)+?
还是直接上代码：
<?php$ip:9501
异步MySQL可以不需要等待第一条查询完成后再执行第二条，在访问不同服务器，不同数据库，不同的表时效果比较明显。
对比同步MySQL查询代码：
<?php$127.0.0.1:9501/
异步查询：
