Multiple GET request to several php file in a web server.
Posted: Tue Sep 19, 2017 7:02 pmHello everyone! I'm sorry for my bad english but I'll try to explain my trouble with an esp8266 developed by dfrobot, this is the store link: https://www.dfrobot.com/product-1279.html.
I'm trying to send datas from my Arduino Mega 2560 to a web server.
Actually I'm be able to make a GET request to send a value to a php file in the web server but I Would like to send several datas using just one GET request. I found on google a way (using the simbol "&" to send 2 values to 2 differents variables in the SAME PHP FILE but I cannot find something about to send several values to different php file wich is my goal!
Is it possible? if not, is there a way to do it (maybe with more GET request) with no close and re-open the connection to the server every value sent? because this take some precoius second.....
I'm using the arduino library ESP8266.h
and this is my sketch:
thanks to who will help me!!!
and if you have some more suggestions about this topic you are welcome to teach me

//the following line is my GET request
