swoole-src: Fatal error: go(): async-io must be used in PHP CLI mode

I have error Fatal error: go(): async-io must be used in PHP CLI mode

1. What did you do? If possible, provide a simple script for reproducing the error. Swoole\Runtime::enableCoroutine(); $s = microtime(true); for ($c = 50; $c--;) { go(function () { $mysqli = new Mysqli('127.0.0.1', 'xxx', 'xxx', 'xxx'); $statement = $mysqli->query('SELECT * FROM (SELECT * FROM shoutboxORDER BYsid) AS shoutboxORDER BYshoutbox.sid ASC'); $i = 0; while ($test = $mysqli->fetch_array($statement)) { echo $i . ' - uid: ' . $test['uid'] . '<br>'; $i++; } }); } Swoole\Event::wait(); echo 'use ' . (microtime(true) - $s) . ' s';

2. What did you expect to see?

Just counting $i and see how it’s performance on my server with swoole
