How to send SMS notification messages via PHP?

[Niheel]

I am trying to setup SMS messaging for a clients app. It's a simple add on where the client will be alerted if certain actions are taken by a user of the application.

How would i set this up?
Do I need special hardware?
Are there third party libraries I can use?
Do i need to signup for a gateway?
Can i get some recommendations for any of these if they are required?

Looks like you may be able to take advantage of the email to SMS gateway of most major carriers:

Otherwise you'll have to purchase an SMS gateway. I've never used one, so I can't help :(

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 http://www.phpjabbers.com/web-sms/ which seems to work a lot easy. Their integration code is pretty simple

<?php
$SMSLIB["phone"] = '44111222333'; // your phone number
$SMSLIB["key"] = 'abcdefghijklmn opqrs'; // 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
?>

Yes, I also suggest you to use an SMS gateway, such as Ozeki NG SMS Gateway!
