I have a logger that I built using the new Uno+Ethernet board. It records data from a bunch sensors, and puts all of the values into a string. I'd like to transmit that string every 10 minutes via the internet to a remote server that's running a php script that will append the incoming string to a text file on the server. The problem is that I can't find any examples of a php script that will do this. I know absolutely nothing about php scripts, so I'm looking for a basic examples that takes the incoming string from the arduino's GET or POST request and just appends it to a text file. I've found enough examples of Arduino sketches to figure out how to transmit the string, I just need help on the php side. Thanks!
