Want to know how easy is to receive SMS with this API? The steps are:

1. Set Path Enviroment if not already done
2. Set POP3 Server account information
3. Create the OSAP Object (Net_SMS class)
4. Retrieve the SMS.

Let's see these steps in code:

<?php
//Set Paths
$delim = (PHP_OS == "WIN32" || PHP_OS == "WINNT") ? ';': ':';
ini_set('include_path', ".{$delim}./pear/" );
unset ($delim);

require_once 'Net/SMS.php';

$sms = new Net_SMS();

//Fill required Params for Receiving
// NOTE: if your mail server uses tls, use the "tls://" prefix.
// It will be used a fake gmail account as example

$params = array('POP3Server' => 'tls://pop.gmail.com',
		'POP3Port' => '995',
		'POP3User' => 'username',
		'POP3Pass' => 'password'
		);
		
//Now Create a Movistar SMS instance
$movistar_sms = $sms->factory('movistar_spain_http',$params);

echo "<pre>";

$r = $movistar_sms->countSMS();
if (PEAR::isError($r)) {
	print_r($r);
}

echo 'Number of Messages: ' . $r . "\n";
echo "<b>Message Id List:</b> \n"; 
print_r($movistar_sms->getSMSIds());
echo '<b>Messages</b>' . "\n";
print_r($movistar_sms->getAllSMS());
echo "</pre>";

?>
