MomentPHP就像一个busybox，可以在极小损耗的情况下实现很多功能
今天，万众瞩目的异步WebSocket出现了！

50行代码，其中只要5行就可以启用WebSocket交互了！
这样，下次我们搭配php-pty就可以实现远程终端...嘿嘿嘿

<?php
use MomentCore\HttpHandle;
use MomentCore\WebSocket;

return function(HttpHandle $handle){ 
    try{
        $handle -> ws() -> then(function(WebSocket $ws){
            $ws -> onMessage(function(string $msg) use ($ws){
                $ws -> send($msg);
            }); 
        });
    }catch(\Throwable $e){}
?>

            var socket = new WebSocket(`ws://${location.host}${location.pathname}`);
            var attachAddon = new AttachAddon.AttachAddon(socket);
            var fitAddon = new FitAddon.FitAddon();

            term.loadAddon(new WebglAddon.WebglAddon());

            term.open(document.getElementById('terminal'));

            window.addEventListener('resize', function(){
                term.fit();
            });
        </script>
    </body>
</html>
<?php } ?>

后记

WebSocket比较难（难在WebSocket的一堆信息头），好在我之前就写好了好用的read和readline，否则像workerman那样还要判断数据是否足够要死的！
