PHP with LabVIEW web services

Does the LabVIEW web Server understand PHP?

Unfortuanately no. it uses a compiled version of EmbedThis Appweb under the hood, and it doesn't support PHP. I've looked in to this quite a bit and couldn't figure out a way to add it, so if you figure something out please let us know!

it would have been very useful, i am trying to use mySQL on a cRIO that is running a LabVIEW web server and PHP would have been very helpful. i am using "system exec.vi" to interact with the database (basically using the Linux RT shell) as the DB connectivity toolkit is not supported on RT targets.

It looks like the source for Appweb is available and PHP support can be added via an addition at compile time. https://embedthis.com/appweb/doc/start/source.html

However, it looks like the NI isn't using the compiled version directly. Maybe it is just renamed, but I'm guessing that source for Appweb is embedded into a larger NI exe.

I've explored this route with no success.

This was my use case as well. Hopefully good things will come in the future that will allow for this.

Depending on your application/use case, a potential solution for this is to add another host as a reverse proxy, put the cRIO on a private network behind the host. Then you can setup IIS/apache/etc and use whatever scripting language you like. This would also give you a more "normal" means to access MySQL from php if you don't need that data on the cRIO directly.
