Question

我收到了这个错误：

警告：socket_select（）：提供的参数不是第12行的/volume1/web/is/xxxx/listen-new.php中的有效Socket资源 PHP警告：socket_select（）：提供的参数不是第12行/volume1/web/is/xxxx/listen-new.php中的有效Socket资源这是我的代码段

我的代码是：

    socket_listen($sock);
    $this->clients[] = $sock;
    $data = array();        
    while (true) {
        $read = $this->clients;
        $write = array(); //NULL
        $except = array();//NULL
        $sckt = socket_select($read, $write, $except, 0);
        if($sckt === false){
             echo "socket_select() failed, reason: " .
                    socket_strerror(socket_last_error()) . "\n";
        }
        elseif($sckt > 0) {
            if (in_array($sock, $read)) {

                    }
                }              
            }
        }
    }
    socket_close($sock);

PS 我还必须更改$write = null和$except = null

对此有什么解决方案吗？

看起来您只提供了服务器代码，但省略了客户端代码。你能发布客户代码吗？我猜问题就在那里。使用我的测试客户端（我使用socket_create），我无法重现您报告的问题。我的也是php7（如果你很好奇）。这可能会为您提供一些提示：Socket_read() says "not a valid resource"

socket_select（）不是有效的套接字
