Catch multiple callbacks and process in one go

[arjan_io]

Hi,

I am trying to build my own weather station. So far I have a Humidity, UV and Baro (all V2) bricklets. I want to process all their data. I have made a PHP script (my best programming skills are PHP) that calls the bricklets one by one, get their value and log it into a mysql database with a timestamp.

 

Would there be a way to use callbacks to do the same? Problem I can't figure out is when all values have been received, aggregate them and send them off.

 

Thanks in advance!
