A few months ago I had a need to do some serial IO from PHP. After asking around I found out there was a PHP extension for this but it was unmaintained, unowned and out of date. To cut a long story short I ended up as the maintainer of said extension and since them I have been fixing and extending it.
The original DIO API is very basic and POSIX oriented. Serial support is not very configurable and doesn’t work at all on Window platforms. So I have been working on implementing PHP stream extensions that allow you to do raw and serial IO via streams. Anyway its ready for testing by people other than me on POSIX (Linux, OS X etc) and Windows platforms so I’m looking for beta testers.
