        $message_to_client = file_get_contents("client_email.html");
        //$message_to_client = "bla bla {{ EMAIL }} bla bla";


        $variables = array(
            'SITE_TITLE' => $SITE_TITLE,
            'SITE_LOGO' => $SITE_LOGO,
            'SITE_URL' => $SITE_URL,
            'CLIENT_NAME' => strip_tags($data->clientname),
            'PHONE' => strip_tags($data->phone),
            'EMAIL' => strip_tags($data->email),
            'CITY' => strip_tags($data->city),
            'REGION' => strip_tags($data->region),
            'COMMENT' => htmlentities($data->comment)                
        );

        $message_to_client = preg_replace_callback('/{{([a-zA-Z0-9\_\-]*?)}}/i',
             function($match) use ($variables) { 
                 return  $variables[$match[1]]; 
        }, $message_to_client );
