我正在尝试在 Google 商务中获取评价。目标是通过 label 进行访问curl，然后从pane.rating.moreReviewslabel中获取值jsaction。

  $html = curl_exec($ch);
  curl_close($ch);
  return $html;

$html = curl("https://www.google.com/maps?cid=12909283986953620003");
$DOM = new DOMDocument();
$DOM->loadHTML($html);
$finder = new DomXPath($DOM);
$classname = 'pane.rating.moreReviews';
$nodes = $finder->query("//*[contains(@jsaction, '$classname')]");
foreach ($nodes as $node) {
  $check_reviews = $node->nodeValue;
  $ses_key = preg_replace('/[^0-9]+/', '', …
