Scrape Amazon.com webpage with PHP - php

Question

I'm trying to simply fetch the html of a remote Amazon url. I had working code, but maybe they changed something? Not sure. I've spent hours trying code samples and plugins from here and there, but nothing is working. Here's what I have right now, but of course it doesn't work either:
$curl = curl_init();
curl_setopt($curl, CURLOPT_URL, $item['URL']);
curl_setopt($curl, CURLOPT_RETURNTRANSFER, 1);
curl_setopt($curl, CURLOPT_FOLLOWLOCATION, 1);
$output = json_decode(curl_exec($curl));
//echo curl_getinfo($curl, CURLINFO_HTTP_CODE);
curl_close($curl);
#file_put_contents($graphics_file_root.'rps/amazon/temp2.html',$output);
$html = new DOMDocument();
#$html->loadHTML($output);
#file_put_contents($graphics_file_root.'rps/amazon/temp.html',$html->saveHTML());
$temp = $html->getElementsByTagName('img');
$html = file_get_contents($item['URL']);
#file_put_contents($graphics_file_root.'rps/amazon/temp2.html',$html);
$temp = $html->getElementsByTagName('img');
echo count($temp);
print_r($temp);
This doesn't work. simple_html_dom doesn't work. Nothing does that I can find.

It looks like some of the code I found online was json specific and removing the json-decode fixed it:
$curl = curl_init();
curl_setopt($curl, CURLOPT_URL, $item['URL']);
curl_setopt($curl, CURLOPT_RETURNTRANSFER, 1);
curl_setopt($curl, CURLOPT_FOLLOWLOCATION, 1);
$output = curl_exec($curl);
//echo curl_getinfo($curl, CURLINFO_HTTP_CODE);
curl_close($curl);
//file_put_contents($graphics_file_root.'rps/amazon/temp2.html',$output);
$html = new DOMDocument();
#$html->loadHTML($output);
//file_put_contents($graphics_file_root.'rps/amazon/temp.html',$html->saveHTML());
$temp = $html->getElementsByTagName('img');
