One of the nice aspects of working in a universitary environment is, that you can take advance of many nice little things. For example, you can send free SMS via the Switch Mailgateway (http://www.switch.ch/mail/)

To do so, I wrote a simple PHP script, wich enables me to send SMS via a little Textbox through a Website. I used the PEAR Framework to implement the mailing- function. For readability I stripped away the HTML forms and JavaScript functions, wich limited the form’s capacity to the SMS- usual 160 characters.

<?php
require_once('Mail.php');

if (isset($_POST['smsor_message'])) {
	$options = array (
		'host'      => 'smtp.unibas.ch',
		'auth'      => false,
	);
	$mailer = Mail::factory('smtp', $options);
	if (true === PEAR::isError($mailer)) {
		die ($mailer->getMessage());
	}
	$headers = array(
		'From' => 'me@unibas.ch',
		'To' => $_POST['smsor_to']."@sms.switch.ch",
	);
	$res = $mailer->send($_POST['smsor_to']."@sms.switch.ch",
				$headers,
				$_POST['smsor_message']);

	if (true === PEAR::isError($res)) {
		die ($res->getMessage());
	}
	echo "Message <br>\n<i>".$_POST['smsor_message']."</i><br>\n
		sent to <i>".$_POST['smsor_to']."</i><br>\n";
	echo "<br><hr><br>";
}
?>
