URL location differences in script between one host to another

I have the following function that retrieves an image from a twitter feed, the parameter "url" is fed a url such as the following:


Because this is a shortened url, the script then returns the location of that url:


The script then parses out the html contents of this page, and returns the source of url elements by tag.

This is a working example of the script:

In this example the images are compared with the entries via time-stamp to the entries existing in the database, if there are no entries with the same time-stamp, they are added, otherwise, they are not.

This is the function that is used:


function getImages($url) {
$url1 = $url;

$response = get_headers($url, 1);
//Get the location property of the first response header.
(returns: http://fb.me/1dnoCICkf)
$location = $response["Location"];
$url3 = $location;

$response2 = get_headers($url3,1);
//Get the location property of the second response header.
(returns: the full facebook url)
$location2 = $response2["Location"];
$url4 = $location2;

//image parser
if(isset($response2["Location"])) { //tests to make sure url is present
$html = file_get_html($url3); //function call to return page as html elements

foreach($html->find('img') as $element) { //finds every img as element
$bump = url_to_absolute($url4, $element->src); //converts src to absolute url
return $bump;
else {
echo "url is not valid (Probably not an image)";


This function works perfectly on 000webhost servers, however on godaddy's servers, it returns NULL. Any help would be greatly appreciated.

if you use cURL on GoDaddy server to get pages, it is necessary for you to specify their proxy server, like this:
