Text messaging has become extremely widespread throughout the world — to the point where an increasing number of web applications have integrated SMS to notify users of events, sales or coupons directly through their mobile devices.

In this tutorial, Kevin Jensen will cover the fundamentals of sending text messages with PHP.

We’ll break this down — one piece at a time:

  • The message is composed using a web application that is stored and executed on a HTTP server and then sent through the internet (“the cloud”) as an email message.
  • The email is received by a Short Message Service Gateway (SMS Gateway), which converts the message from an email message to a SMS message.
  • The SMS message is then handed to a Short Message Service Center (SMSC), which is a server that routes data to specific mobile devices.
  • The message is finally transmitted over the wireless network to the recipient.

Most wireless networks have a SMS gateway through which email messages can be sent as text messages to a mobile device. This is nice, because, from a developer’s standpoint, it is generally free—however, it is of course not a free service for the end user. Fees still apply to the recipient of the message and messages sent via email will be billed as a non-network text message
