function get_web_page( $url )
    {               
            $options = array(
            CURLOPT_RETURNTRANSFER  => true, 
            CURLOPT_HEADER          => false,
            CURLOPT_FOLLOWLOCATION  => true, 
        );

        $ch      = curl_init( $url );
        curl_setopt_array( $ch, $options );
        $content = curl_exec( $ch );
        curl_close( $ch );

        return $content;
}

echo get_web_page("http://www.emirates.com/account/english/miles-calculator/miles-calculator.aspx?org=BOM&dest=JFK&trvc=0&h=7b1dc440b5eecbda143bd8e7b9ef53a27e364b");
