Hey Timo…! There is no PHP SMF library that I know of? I’m not sure if there’s some way to “wrap” another API to use with PHP (like wrapping C API to use with Python). Do you have to use PHP?
A possible future option would be to use a REST Delivery Point, and REST Consumer, which essentially means the broker will “webhook” out a message from a queue to a REST URL. This doesn’t exist yet though.
I’ll go do some looking about PHP options.
