I am trying to make a sitescraper. I made it on my local machine and it works very fine there. When I execute the same on my server, it shows a 403 forbidden error. I am using the PHP Simple HTML DOM Parser. The error I get on the server is this:

Warning: file_get_contents(http://example.com/viewProperty.html?id=7715888) [function.file-get-contents]: failed to open stream: HTTP request failed! HTTP/1.1 403 Forbidden in /home/scraping/simple_html_dom.php on line 40

The line of code triggering it is:

$url="http://www.example.com/viewProperty.html?id=".$id;

$html=file_get_html($url);

I have checked the php.ini on the server and allow_url_fopen is On. Possible solution can be using curl, but I need to know where I am going wrong.
