感觉是连接已经关闭后执行了join操作导致。
https://github.com/walkor/phpsocket.io/blob/master/src/Socket.php

     public function join($room)
     {
        if(isset($this->rooms[$room])) return $this;
        $this->adapter->add($this->id, $room);
        $this->rooms[$room] = $room;
        return $this;
    }

改成

     public function join($room)
     {
        if (!$this->connected) return $this;
        if(isset($this->rooms[$room])) return $this;
        $this->adapter->add($this->id, $room);
        $this->rooms[$room] = $room;
        return $this;
    }

试下看下还是否报错

错误出现了很多次，join这里的错误。 emit 执行没有错误。

https://github.com/walkor/phpsocket.io/blob/master/src/Socket.php 里 join方法加一句if (!$this->connected) return $this;

好的，谢谢。
