Continuing on from a previous post on multi-threading in PHP, Brian Bosh is back with something a bit more developed that will allow for communication between the threads as well.

Earlier this week, I suggested PHP could be multithreaded. The sample I provided was very simple and at least one reader quickly wondered how to communicate with threads. If you haven't already, take a look at part 1 to get some basic information about threads in PHP.

It took a bit longer to get that part working that simple threads, but as of now, I have a functional prototype of an HVAC thread.

The post is broken up into five different files to make things work:

• an overall class for the main functionality (their example of running the heater or AC)
• a class to create and set up a thread
• a "thready utility" class to handle the response from a thread
• a thread library to handle creation/interaction/etc
• the example file of the system in use

Following the code, he gives a nice explanation of how things work and how they all fit together.
