This month’s issue of php[architect] is free thanks to Nexmo. This month the focus is on API’s:
The promise of Application Programming Interfaces (APIs) is really bearing fruit in today’s Web. Of course, we are not talking about internal APIs but of HTTP-based ones that allow us to interact with external systems—whether its saving or searching images in Flickr, getting weather conditions, or transcoding video. For many tasks, if you sign up to use the right APIs, you can build a fully functional application by writing PHP scripts which coordinate the workflow and communications between APIs.
If you haven’t checked out the magazine before, now is a great time.
