从远程站点加载内容不起作用，但原因

我仍在为客户端处理此目录，该目录通过PHP和Simple DOM解析器从远程站点加载图像。

// Code excerpt from http://internetvolk.de/fileadmin/template/res/scrape.php, this is just one case of a select
$subcat = $_GET['subcat'];
$url = "http://pinesite.com/meubelen/index.php?".$subcat."&lang=de";
$html = file_get_html(html_entity_decode($url));
$iframe = $html->find('iframe',0);
$url2 = $iframe->src;
$html->clear(); 
unset($html);
$fullurl = "http://pinesite.com/meubelen/".$url2;
$html2 = file_get_html(html_entity_decode($fullurl));
$pagecount = 1;
$titles = $html2->find('.tekst');
$images = $html2->find('.plaatje');
$output='';
$i=0;
foreach ($images as $image) {
$item['title'] = $titles[$i]->find('p',0)->plaintext;
$imagePath = $image->find('img',0)->src;
$item['thumb'] = resize("http://pinesite.com".str_replace('thumb_','',$imagePath),array("w"=>225, "h"=>162));
$item['image'] = 'http://pinesite.com'.str_replace('thumb_','',$imagePath);
$fullurl2 = "http://pinesite.com/meubelen/prog/showpic.php?src=".str_replace('thumb_','',$imagePath)."&taal=de";
$html3 = file_get_html($fullurl2);
$item['size'] = str_replace('  ','',$html3->find('td',1)->plaintext);
unset($html3);
$output[] = $item;
$i++;
}
if (count($html2->find('center')) > 1) {
// ok, multi-page here, let's find out how many there are
$pagecount = count($html2->find('center',0)->find('a'))-1;
for ($i=1;$i<$pagecount; $i++) {
$startID = $i*20;
$newurl = html_entity_decode($fullurl."&beginrec=".$startID);
$html3 = file_get_html($newurl);
$titles = $html3->find('.tekst');
$images = $html3->find('.plaatje');
$a=0;
foreach ($images as $image) {
$item['title'] = $titles[$a]->find('p',0)->plaintext;
$item['image'] = 'http://pinesite.com'.str_replace('thumb_','',$image->find('img',0)->src);
$item['thumb'] = resize($item['image'],array("w"=>225, "h"=>150));
$output[] = $item;
$a++;
}
$html3->clear();
unset ($html3);
}
}
echo json_encode($output);

那么它应该做什么(以及对某些类别的作用(：从此页面输出图像，标题和缩略图：http://pinesite.com

例如，如果您向其传递"？function=images&subcat=

antiek"，则此方法有效，但如果向其传递"？function=images&subcat=stoelen"则无效。我什至不认为这是远程页面的问题，所以我的代码中一定有错误。
