PHP:

 

Are you setting $auction (line 4) somewhere? Have you tried outputting the URL before trying to fetch the page so you can verify it is correct? You ought to use a class instead of these functions that all access the same globals.

 

search.ebay.com/iphone_W0QQca...ocusZbs=hybird cars

should be

search.ebay.com/iphone_W0QQca...ocusZbs=hybird%20cars
spaces aren't allowed in URLs when using fopen.
