How can i get values from arduino output to php page ???
what about HTTP request ??
What external communication mechanisms does your Arduino have available?
ethernet shield
You could write your sketch to act as an HTTP client and post the data to the PHP webapp via a simple page that just receives the posted data. Have the webapp save the data somewhere (in memory would be OK if the data is volatile, but a database would be the obvious choice if you need to persist it) and then retrieve the data from storage when it serves out the pages displaying it.
