After PHP processes the request on a website, it closes all connections. Most SMPP providers do not want you to open and close connections, you should keep them alive and send enquire_link commands periodically. Which means you probably need to get some kind of long running process, ie. using the [process control functions](http://www.php.net/manual/en/book.pcntl.php), and implement a form of queue system which you can push to from the website. This requires shell level access to the server, and knowledge of unix processes. + +**How do I receive delivery receipts or SMS'es?** +To receive a delivery receipt or a SMS you must connect a receiver in addition to the transmitter. This receiver must wait for a delivery receipt to arrive, which means you probably need to use the [process control functions](http://www.php.net/manual/en/book.pcntl.php). + +We do have an open source implementation at [php-smpp-worker](https://github.com/onlinecity/php-smpp-worker) you can look at for inspiration, but we cannot help you with making your own. Perhaps you should look into if your SMSC provider can give you a HTTP based API or using turnkey software such as [kannel](http://www.kannel.org/), this project provides the protocol implementation only and a basic socket wrapper. + **I can't send more than 160 chars** There are three built-in methods to send Concatenated SMS (csms); CSMS_16BIT_TAGS, CSMS_PAYLOAD, CSMS_8BIT_UDH. CSMS_16BIT_TAGS is the default, if it don't work try another. |
