Php 使用simple_html_dom&cURL，但没有获得页面的所有内容。我怎样才能得到它？

问题是，我得到了部分内容，但没有得到用户的评论。通过Firebug，我看到了内容，但当我检查源代码时，HTML标记内没有内容/没有相同的HTML标记。这是我的密码：

<?php
    //Headers 
    include('simple_html_dom.php');

function getPage($page, $redirect = 0, $cookie_file = '')
{         
   $ch = curl_init();


   $headers = array("Content-type: application/json");
   curl_setopt($ch, CURLOPT_HTTPHEADER, $headers); 

   curl_setopt($ch, CURLOPT_RETURNTRANSFER, 1);
   curl_setopt($ch, CURLOPT_SSL_VERIFYPEER, 0);
   curl_setopt($ch, CURLOPT_SSL_VERIFYHOST, 1);
   curl_setopt($ch, CURLOPT_HEADER, 0);

   if($redirect)
   {
      curl_setopt($ch, CURLOPT_FOLLOWLOCATION, 1);    
   }

   curl_setopt($ch, CURLOPT_URL, $page);

   if($cookie_file != '') {
     curl_setopt($ch, CURLOPT_COOKIEJAR,  $cookie_file);
     curl_setopt($ch, CURLOPT_COOKIEFILE, $cookie_file);
   }

   curl_setopt($ch, CURLOPT_USERAGENT, 'Mozilla/5.0 (Windows; U; Windows NT 5.1; en-US; rv:1.8.0.6) Gecko/20060728 Firefox/1.5.0.6');

   $return = curl_exec($ch);  //Mozilla/4.0 (compatible;)

   curl_close($ch);

   return $return;

}//EO Fn

//Source 
$url = 'http://www.vitals.com/doctor/profile/1982660171/reviews/1982660171';


//Parsing ... 
$contents = getPage($url, 1, 'cookies.txt'); 

$html = str_get_html($contents); 
//Output
echo $html->outertext;
?>

有人能帮我吗？我应该怎么做才能得到整个页面，这样我就可以抓取评论了？在这里输入代码

它们只是作为JSON存储在页面顶部的一个块中。用正则表达式或简单的HTMLDOM解析它，并运行它

但同样，请确保您有权限这样做…

我打赌这些评论是使用Ajax添加的。这个问题没有简单的解决办法——加上你可能只是在学习刮片——在这个领域也是非常新的。简单的页面我可以。你能给我写一些代码来解释如何用简单的HTML DOM或正则表达式解析这个变量json={。
