The SMS class provides a simple way to create a Web-based SMS gateway using the aspsms.com SMS service.
Disclaimer: This is quite old code, so it may not be using all the latest PHP functionality.
In order to use the SMS class, you need to have an account at aspsms.com. You also need to make sure that your web server is able to access xml1.aspsms.com and xml2.aspsms.com on ports 5061 and 5098. By default, all IP addresses are able to access these servers. However, you can restrict the addresses that are able to connect using your username and password on the aspsms.com web site. Also make sure that traffic originating from your web server is not blocked by firewalls or other filters.
Once you have your username, password and a confirmation that your IP address is able to access the SMS gateway, our SMS class is very easy to use:
require("SMS.php");
$sms = new SMS("username", "password");
$sms->setOriginator("...");
$sms->addRecipient("...");
$sms->setContent("An SMS message.");
$result = $sms->sendSMS();
if ($result != 1) {
$error = $sms->getErrorDescription();
}The constructor creates a new SMS object using your personal username and password (received from aspsms.com). The string set by setOriginator is your phone number or your name (since this string is not verified by the aspsms service, you may start to mistrust the sender of messages...). You can then add recipients' phone numbers with the addRecipient method. Note that the phone numbers are international numbers, including the country code. The setContent method sets the message to send (160 characters max.) and sendSMS finally sends the message to the recipients.
An example for testing the class is provided in the file example.php.
The SMS class also offers access to the following extended features offered by aspsms.com:
-
Multiple Recipients: If you call the addRecipient method multiple times, an SMS will be sent to multiple recipients at once.
-
Flashing SMS: Call the setFlashing method to make this a flashing SMS. Try this option to see what it looks like on your mobile phone.
-
Blinking SMS: Call the setContent method with a second parameter that evaluates to true. This will cause all text inside brackets to blink. This option may not work on all mobile phones.
-
VCard: By calling the sendVCard method, a VCard can be sent to a mobile phone.
-
Logo: You need to set the MCC and MNC, and then call the setLogo method to set an URL to a 72x14 pixels BMP image. Finally, use the sendLogo method instead of sendSMS to send the logo. Check the aspsms documentation for more information.
-
Credits: In order to see how many credits you have left, use the following code:
$sms = new SMS("username", "password");
$sms->showCredits();
print $sms->getCredits();- Deferred delivery can be done using the setDeferred method. The date and time of the delivery are given in the format ddmmyyyyhhmmss. Note that you also need to set the timezone using the setTimezone method if you use this functionality. By default, the aspsms.com servers will assume you are in the GMT+1 timezone:
$sms->setTimezone("+4");
$sms->setDeferred("18092007140000");aspsms.com supports delivery status notification that lets you know if a message has been delivered to a recipient or not. As soon as the status of a message changes (e.g. when it is sent to the recipient), the aspsms.com server notifies you by calling a specific URL.
In order to use delivery status notifications using PHPASPSMS, the following needs to be done:
- A unique identifier needs to be assigned to every (SMS,Recipient) pair. You can pass this information to PHPASPSMS when you add a recipient:
$sms->addRecipient($recipient_phonenumber, $unique_id);Note that the second argument is optional. Not setting it disables the delivery status notification feature.
- Next, you need to provide three URLs that will be called by the aspsms.com server once the delivery status is known:
$sms->setBufferedNotificationURL("http://domain.com/sms.php?buf=");
$sms->setDeliveryNotificationURL("http://domain.com/sms.php?ok=");
$sms->setNonDeliveryNotificationURL("http://domain.com/sms.php?no=");These URLs will be called to indicate that an SMS has been buffered, delivered, or that the aspsms.com server was unable to deliver it. The unique identifier defined using the addRecipient method will be appended to this URL. Your application then knows what happened to the message.
Although this is not documented in the official documentation of the aspsms.com XML Interface, the following placeholders will be replaced inside a URL:
- Recipient mobile number
- Service center times tamp (Submission date)
- Delivery service center times tamp (Notification date)
- Reason code
- Delivery status
- Transaction identifier (the unique identifier specified with addRecipient)
For a comprehensive list of "Reason code" and "Delivery status", please refer to the ASPSMS Documentation. Please note that if no is given in the URL, the unique identifier will be appended to the URL.
