php-smpp library can be used to make SMPP requests using PHP. This library's higher-level functions can be used to synchronously submit SMS to an SMS gateway or SMSC.
SMPP requirements and resources
SMPP is the Short Message Peer-to-Peer protocol and is used by applications for sending and receiving SMS. An SMPP client can be used to connect to an SMSC or SMS gateway using the SMPP protocol. An SMPP account, including special Developer accounts, can quickly and easily be obtained for using the Melrose Labs Tyr SMS Gateway or SMSC Simulator. The following are required to send SMS with SMPP:
- SMPP Protocol [reference]
Short Message Peer-to-Peer Protocol v3.3, v3.4 and v5 specifications and guides
- SMPP Client [tool]
Browser-based SMPP client supporting SMPP v3.x and v5 via Web Sockets
PHP requirements and resources
PHP is a programming language and can be used to quickly and easily add SMS support for programmatically sending and receiving SMS messages. Use it for transactional messaging and notifications between your application and mobiles. The following are required to send SMS using PHP:
PHP programming/scripting language
Requirements and resources
The following are required to send SMS with SMPP using PHP:
PHP-based SMPP client library for sending and receiving SMS using SMPP v3.4
PHP socket extension
Create the file
sendsms.php containing the code below. Replace the hostname
PASSWORD values with those from your SMPP API account. Alternatively, replace
PASSWORD with those allocated to you for use with the Melrose Labs SMSC Simulator.
The following example PHP code opens an SMPP transmitter bind to
smscsim.melroselabs.com on port
2775 (SMPP port), and then sends the message
Hello World #$£ to mobile number
MelroseLabs. The message ID returned in
$messageID is that returned from the SMS gateway or SMSC after a successful submission. The SMPP system ID and password for the SMPP account are contained in
<?php require_once 'smppclient.class.php'; require_once 'gsmencoder.class.php'; require_once 'sockettransport.class.php'; // Construct transport and client $transport = new SocketTransport(array('smscsim.melroselabs.com'),2775); $transport->setRecvTimeout(10000); $smpp = new SmppClient($transport); // Open the connection $transport->open(); $smpp->bindTransmitter("SYSTEMID","PASSWORD"); // Prepare message $message = 'Hello World €$£'; $encodedMessage = GsmEncoder::utf8_to_gsm0338($message); $from = new SmppAddress('MelroseLabs',SMPP::TON_ALPHANUMERIC); $to = new SmppAddress(447712345678,SMPP::TON_INTERNATIONAL,SMPP::NPI_E164); // Send $messageID = $smpp->sendSMS($from,$to,$encodedMessage); // Close connection $smpp->close(); ?>
To receive delivery receipts, use a transceiver bind instead of a transmitter bind, or have a receiver bind in addition to a transmitter bind.
