问如何使用mikrotik检索mikrotik PPPoE服务器服务名称列表？

EN

$ctype =$this->uri->segment('3');
if($ctype=='PPP')
{
  if ($this->routerosapi->connect('1.1.1.1', 'xxx', 'xxx')) 
  {
    $this->routerosapi->write('/interface/pppoe-server/getall');
    $READ = $this->routerosapi->read(false);
    $mktserver= $this->routerosapi->parseResponse($READ);  
    $this->routerosapi->disconnect();
  }
}
elseif($ctype=='HSP')
{
  if ($this->routerosapi->connect('xxx', 'xxx', 'xxx')) 
  {
    $this->routerosapi->write('/ip/hotspot/server/getall');
    $READ = $this->routerosapi->read(false);
    $mktserver= $this->routerosapi->parseResponse($READ);  
    $this->routerosapi->disconnect();
  }
}  
<p>
    <label for="simple-required">Server</label>
    <select name="server" id="server" class="full-width">
    <?php foreach($mktserver as $item):?>
    <option value="<?php echo $item['service-name'];?>"><?php echo $item['service-name'];?></option>
    <?php endforeach;?>
</select>
