Retrieving Remote HTML content from DFF Server
For increased security, DFF will now recommend using the function file_get_contents() or cURL instead of include();
Remote inclusion of remote PHP file or any remote file is a security hole in PHP. It has worked well for DFF for almost 3 years because the files affiliates are including from DFF are not malicious. Nevertheless it is not best practice.
if you are getting errors using remote URL include such as:
Warning: include() [function.include]: URL file-access is disabled in the server configuration in ...
[function.include]: failed to open stream: no suitable wrapper could be found ...
Warning: include() [function.include]: Failed opening 'http://www.datafeedfile.com

Using PHP
Instead of using:
include("http://www.datafeedfile.com/some_dff_script.php?affid=...&".$_SERVER['QUERY_STRING']);
DFF recommends change to:
echo file_get_contents("http://www.datafeedfile.com/some_dff_script.php?affid=....&".
$_SERVER['QUERY_STRING']);
or you can use the cURL library/extension like this:
$ch = curl_init
("http://www.datafeedfile.com/some_dff_script.php?affid=....&".
$_SERVER['QUERY_STRING']);
curl_setopt
($ch, CURLOPT_RETURNTRANSFER,
TRUE);
if(($DFF_output = curl_exec
($ch))===
FALSE) die("Error getting content from DFF");
else echo $DFF_output;
curl_close
($ch);
