PHP - Weird file_get_contents behavior

When I run the first code it works well. The echo works. 

<?php
$html = file_get_contents('https://feedback.aliexpress.com/display/productEvaluation.htm?productId=32795887882&ownerMemberId=230515078&withPictures=true&i18n=true&Page=3'); 
$dom = new domDocument;
$dom->loadHTML($html);
$dom->preserveWhiteSpace = false;
$images = $dom->getElementsByTagName('img');
foreach ($images as $image) {
echo $image->getAttribute('src');
echo "<br>";
}
?>

But when I try the following code and running it with parameters nothing is returned:

index.php?url=https://feedback.aliexpress.com/display/productEvaluation.htm?productId=32795887882&ownerMemberId=230515078&withPictures=true&i18n=true&Page=3

<?php

$html = file_get_contents($_GET["url"]);
$dom = new domDocument;
$dom->loadHTML($html);
$dom->preserveWhiteSpace = false;
$images = $dom->getElementsByTagName('img');
foreach ($images as $image) {
echo $image->getAttribute('src');
echo "<br>";
}
?>

Anyone got any idea?

Update:

Probally not the best and cleanest solution, but it works :) 

<?
$url = urldecode($_GET['url']);
$ownerMemberId = urldecode($_GET['ownerMemberId']);
$withPictures = urldecode($_GET['withPictures']);
$page = urldecode($_GET['Page']);

$newurl = $url . "&ownerMemberId=" . $ownerMemberId . 
"&withPictures=true&i18n=true&Page=" . $page;

$html = file_get_contents($newurl);
$dom = new domDocument;
$dom->loadHTML($html);
$dom->preserveWhiteSpace = false;
$images = $dom->getElementsByTagName('img');

foreach ($images as $image) {
echo "<img src='";
echo $image->getAttribute('src');
echo "'>";
echo "<br>";
}

?>

Please decode the url as it is sending another url. 

$url = urldecode($_GET['url']);
$html = file_get_contents($url);
$dom = new domDocument;
$dom->loadHTML($html);
$dom->preserveWhiteSpace = false;
$images = $dom->getElementsByTagName('img');

foreach ($images as $image) {
    echo $image->getAttribute('src');
    echo "<br>";
}

Hope that works for you.
