You can send free sms messages formatted as an email in North America and possibly in other countries as well. In Asia it seems that they aren't free.

Of course it is possible, you can add web sms functionality to any web application or website. You need to connect your application to SMS Gateway. Most SMS gateways provide external API which can be used to do that. They usually have documentation which you can use to find out how to integrate SMS notification in your PHP code. Unfortunately there are no reliable free sms service provides so you have to pay for this sms service. You can check [snipped] which seems to work a lot easy. Their integration code is pretty simple

<?php
$SMSLIB["phone"] = '44111222333'; // your phone number
$SMSLIB["key"] = 'abcdefghijklmnopqrs'; // your personal API code
include("smslib.php"); // we will provide you with smslib.php file
sendSMS("test message", $SMSLIB["phone"]); // function which sends the message
?>
