Sub domain name handle in htaccess

[webmoster]

Help me! I have a domain, I would like to handle subdumain with .htaccess file.

for example: http://usa.hotbizzle.com or http://india.hotbizzle.com should not redirect to sub folder. URL should not change in the browser but it has to call a file php file and give result. Is there any possibilities in .htaccess or php.ini file?

Try this PHP code,

<?php
// create a new cURL resource
$ch = curl_init();

// set URL and other appropriate options
curl_setopt($ch, CURLOPT_URL, "http://www.example.com/");
curl_setopt($ch, CURLOPT_HEADER, 0);

// grab URL and pass it to the browser
curl_exec($ch);

// close cURL resource, and free up system resources
curl_close($ch);
?>

thanx vijykmar, but my problem is subdumain name should not change in the browser, and subdomain name has to go as internal parameter into a php file. i mean all subdomains are going to call single php file only. i'm looking for .htaccess or php.ini solution.
