Advanced Services - SMS Connectivity PHP Sample application using HTTP to send an SMS text message |
|
The following sample application written in PHP sends an SMS text message to a single mobile telephone. The application uses HTTP to communicate with HSL's systems. To send to more than one mobile telephone at a time, separate each mobile number in the destaddr field by a comma (e.g. "447968000111,447720000111,3378100100").

<?php
// These variables fill out the various parts described in the interface
// specification
$host = 'sms.haysystems.com';
$port = '80';
$action = 'sendtxt';
$client_id = '<your client_id>';
$text = 'this is a test message';
$destaddr = '<some fully-qualified MSISDN>';
$secret = '<your secret>';
// Compute the MD5 hash (digest)
$hash = md5($secret . $text . $destaddr);
// Build and encode the URL.
// Note we are careful to URL-encode the message content as it is the only part
// of the URL likely to contain reserved characters.
$url = "http://$host:$port/$action/?client_id=$client_id&text="
. urlencode($text) . "&destaddr=$destaddr&key=$hash";
// Make the HTTP call (you could use CURL on PHP 4+) we nab the content that
// readfile would normally output directly with the ob_start, ob_get_contents
// and ob_end_clean calls.
ob_start();
$result = @readfile($url);
$data = ob_get_contents();
ob_end_clean();
// Examine the results
if($result === false) {
echo '<p>Could not make HTTP request; is the URL correct?</p>';
echo "<p>$url</p>";
} else {
echo "<p>Submission result: $data</p>";
}
?>
