Php 解析信息

我试图解析有关手机的信息。需要电话：链接，名称，价格，照片现在我有：链接，名称，价格。所以我只需要一点点。我的代码现在如下所示：

h2>Telefonai Varle su photo</h2>
</br>
<?php
include_once('simple_html_dom.php');
 $url = "https://www.varle.lt/mobilieji-telefonai/";

// Start from the main page
$nextLink = $url;

// Loop on each next Link as long as it exsists
while ($nextLink) 
{
    echo "<hr>nextLink: $nextLink<br>";
    //Create a DOM object
    $html = new simple_html_dom();
    // Load HTML from a url
    $html->load_file($nextLink);

      $phones=$html->find();
       /////////////////////////////////////////////////////////////
       /// Get phone blocks and extract info (also insert to db) ///
      /////////////////////////////////////////////////////////////
      $phones = $html->find('a[data-id]');

    foreach($phones as $phone) 
    {
        // Get the link
        $linkas = $phone->href;
        // Get photo
        $foto= $phone->find('span[data-original]', 0)->plaintext;
        // Get the name
        $pavadinimas = $phone->find('span[class=inner]', 0)->plaintext;
        $pavadinimas = str_replace("Išmanusis telefonas"," ",$pavadinimas);


        // Get the name price and extract the useful part using regex
        $kaina = $phone->find('span[class=price]', 0)->plaintext;

        preg_match('@(\d+),?@', $kaina, $matches);
        $kaina = $matches[1];

        echo $pavadinimas, " #----# ", $kaina, " #----# ", $linkas,  " nuotrauka " ,  $foto         ,"<br>";

        //$query = "insert into telefonai (pavadinimas,kaina,parduotuve,linkas,foto) VALUES (?,?,?,?,?)";
       //$this->db->query($query, array($pavadinimas,$kaina,"Varle.lt", $linkas,"https://www.varle.lt"+$foto));
    }

    /////////////////////////////////////////////////////////////
    /////////////////////////////////////////////////////////////

    // Extract the next link, if not found return NULL
    $nextLink = ( ($temp = $html->find('div.pagination a[class="next"]', 0)) ?      "https://www.varle.lt".$temp->href : NULL );

    // Clear DOM object
    $html->clear();
    unset($html);
 }
 ?>

要检索评级，您必须计算span[class=rating]中span[class=selected]的数量

$rating = count($phone->find('span[class=rating]')->find('span[class=selected]'));

那手机照片呢？这不起作用。致命错误：对中的非对象调用成员函数find（）
$rating = count($phone->find('span[class=rating]')->find('span[class=selected]'));
