How do I download a file from an .ashx page with php? - php

Question

I am trying to download a file from this url in php: http://www.roblox.com/Asset/BodyColors.ashx?userId=36377783
The page returns a file your webbrowser automatically downloads.
I tried using cURL:
<?php
$uid = 36377783;
$xUrl = "http://www.roblox.com/Asset/BodyColors.ashx?userId=".$uid;
$ch = curl_init();
curl_setopt($ch, CURLOPT_URL, $xUrl);
curl_setopt($ch, CURLOPT_FOLLOWLOCATION, true);
curl_setopt($ch, CURLOPT_RETURNTRANSFER, true);
curl_setopt($ch, CURLOPT_HEADER, false);
curl_setopt($ch, CURLOPT_SSL_VERIFYHOST, false);
$xml = curl_exec($ch);
curl_close($ch);
echo $xml;
?>
But it redirects me to an error page.
How do I download the file the .ashx url returns?
(Setting CURLOPT_USERAGENT doesn't work.)

There is a redirection - i use file_get_contents() (but why not curl) and $http_response_header:
$uid = 36377783;
$xUrl = "http://www.roblox.com/Asset/BodyColors.ashx?userId=".$uid;
$opts = array(
'http'=>array(
'method'=>"GET",
'follow_location' => true,
'header'=>
"Host: www.roblox.com\r\n" .
"User-Agent: Mozilla/5.0 (Windows NT 6.1; WOW64; rv:43.0) Gecko/20100101 Firefox/43.0\r\n" .
"Accept: text/html,application/xhtml+xml,application/xml;q=0.9,*/*;q=0.8\r\n" .
"Accept-Encoding: gzip, deflate\r\n" .
"DNT: 1\r\n"
)
);
$context = stream_context_create($opts);
$xml = file_get_contents($xUrl, false, $context);
#print_r($http_response_header);
$url_redirect = str_replace('Location: ',"",$http_response_header[5]);
#print $url_redirect;
$xml = file_get_contents($url_redirect);
#print_r($xml);
$roblox_responses = new SimpleXMLElement($xml);
print_r($roblox_responses);
