Here's a bit of PHP that you can execute on your own domain to
retrieve data from other domains:
<?php
$session=curl_init('path to remote data source here');
curl_setopt($session, CURLOPT_HEADER, false);
curl_setopt($session, CURLOPT_FOLLOWLOCATION, true);
curl_setopt($session, CURLOPT_RETURNTRANSFER, true);
$response=curl_exec($session);
header("Content-Type: text/xml"); // assuming remote data is XML
format otherwise change the header appropriately
echo $response;
curl_close($session);
?>
PHP CURL reference page is here:
http://php.net/manual/en/book.curl.php
Check out the reference page for CURL options - the code snippet above
may not have options set as you require:
http://www.php.net/manual/en/function.curl-setopt.php
So create a PHP script with the above code snippet and instead of your
API code requesting data from a domain other than yours, you call the
PHP CURL script instead.
You could make the script dynamic - instead of hard coding the 'path
to remote data source here' you could pass the remote data source URL
to the script:
<?php
$data_source=$_GET['url'];
$session=curl_init($data_source);
curl_setopt($session, CURLOPT_HEADER, false);
curl_setopt($session, CURLOPT_FOLLOWLOCATION, true);
curl_setopt($session, CURLOPT_RETURNTRANSFER, true);
$response=curl_exec($session);
header("Content-Type: text/xml");
echo $response;
curl_close($session);
?>
So your API code could make a request for remote data from the CURL
script such as:
http://my_domain.com/my_curl_script.php?url=url_to_remote_data
Where "url_to_remote_data" is a properly encoded path to the remote
data source.
