<?php
// Include the class
require 'class.swd_SMS.php';

// Create the object. (Parameters are optional if they're set in the class already)
$SMS = new swd_SMS('username', 'password');

// Send SMS. First parameter is the cell phone number with country code. (Without leading 00)
$SMS->send('34123456789', 'The message goes here');

// Let's send another just for fun
$SMS->send('34987654321', 'The message goes here');

// All sent messages are stored in an array.
echo '<pre>' . print_r($SMS->sent_messages, true) . '</pre>';


// Each sent message has a unique message ID, which is in the array above as well. With this we can see the message status any time. Like this:

$status = $SMS->fetch_msg_status('MT0052355965-1');

echo '<pre>' . print_r($status, true) . '</pre>';
?>

Thanks for this excellent piece of code. I was struggling with some out of date code with no success, then I found this. It enabled me to write an IRC bot that sends me an SMS when someone joins my IRC room.
