我的错误是：

注意：未定义的变量：在第 21 行的 C:\xampp\htdocs\server4.php 中返回

第 21 行是：

   $return .= fgets($this->_socket);

注意：未定义的偏移量：第 95 行 C:\xampp\htdocs\server4.php 中的 0

注意：未定义的偏移量：第 95 行 C:\xampp\htdocs\server4.php 中的 0

第 95 行是：

$serverInfo = $master->server_getInfo($serverList[0]['ip'], $serverList[0]['port']);

和我的完整代码：

<?php
class Q3Master
{
    private $_socket;
    private $_port = '20810';
    private $_host;

    public function __construct($masterHost)

            stream_set_blocking($this->_socket,0);
    }

    public function master_listServers($timeout = '1')
    {
            fputs($this->_socket,str_repeat(chr(255),4).'getservers 69 empty full demo'."\n");

            $time=time()+$timeout;
            while($time > time() || strpos($return,'EOT') === FALSE)
            {
                    $return .= fgets($this->_socket);

您需要$return在使用它之前进行定义，因为如果while不执行循环$return未定义，因此不能用作explode().

$return = ''; // <-- define it as an empty string

while($time > time() || strpos($return,'EOT') === FALSE)
{
       $return .= fgets($this->_socket);
}
$return = explode('\\',$return);

注意：未定义的变量：在第 21 行的 C:\xampp\htdocs\server4.php 中返回

然后定义该变量：$return = null.

注意：未定义的偏移量：第 95 行 C:\xampp\htdocs\server4.php 中的 0

然后定义该 offset: $serverList[0] = array('ip' => null, 'port' => null)，或者在使用它之前检查是否定义了偏移量：

if (isset($serverList[0])) {
  $serverInfo = $master->server_getInfo($serverList[0]['ip'],
                                        $serverList[0]['port']);
}

但首先你应该调查为什么你期望$return和$serverList[0]被定义。也许这些变量应该由代码的不同部分提供，那是被破坏的。

使用以下命令添加 var 返回的初始化：

$return = '';

尝试这个：

public function master_listServers($timeout = '1')
    {
            $return = '';
            fputs($this->_socket,str_repeat(chr(255),4).'getservers 69 empty full demo'."\n");

            $time=time()+$timeout;
            while($time > time() || strpos($return,'EOT') === FALSE)
            {
                    $return .= fgets($this->_socket);
            }
            $return = explode('\\',$return);
            unset($return[0]);
            unset($return[count($return)]);
            $iplist = array();
            foreach($return as $server)
            {
                    for($i = 0;$i < 4;$i++)
                            $addr[] = ord($server[$i]);

                    for($i = 4;$i < 6;$i++)
                            $port .= dechex(ord($server[$i]));
                    $port = hexdec($port);
                    $iplist[] = array('ip' => join('.',$addr),'port' => $port);
                    unset($addr);
                    unset($port);
            }

            return $iplist;
    }
