Answer 1

Base on Leigh Simpson, It works, but I need query string attach with it. That's what I work around:

<?php
$ch = curl_init();
curl_setopt($ch, CURLOPT_URL, "http://xxx.xxx.xxx.xxx/index.php?page=api&action=getdifficulty");
curl_setopt($ch, CURLOPT_HTTPHEADER, array('Host: subdomain.hostname.com'));
curl_setopt($ch, CURLOPT_RETURNTRANSFER, true);
echo curl_exec($ch);
?>

Answer 2

You can set the host header in the curl request:

<?php
$ch = curl_init('XXX.XXX.XXX.XXX');
curl_setopt($ch, CURLOPT_HTTPHEADER, array('Host: subdomain.hostname.com'));
curl_setopt($ch, CURLOPT_RETURNTRANSFER, true);
echo curl_exec($ch);

Answer 3

For HTTPS sites use CURLOPT_RESOLVE which exists in every PHP version since PHP 5.5.

<?php
$ch = curl_init('https://www.example.com/');
// note: array used here
curl_setopt($ch, CURLOPT_RESOLVE, array(
    "www.example.com:443:172.16.1.1",
));
curl_setopt($ch, CURLOPT_RETURNTRANSFER, true);
curl_setopt($ch, CURLOPT_VERBOSE, true);
$result = curl_exec($ch);

Sample output:

* Added www.example.com:443:172.16.1.1 to DNS cache
* Hostname www.example.com was found in DNS cache
*   Trying 172.16.1.1...
