Read data from DHT11 and post using HTTP POST through sim808

I have a SIM808 GPRS/GSM module and a DHT11 temperature & humidity sensor. How can i create a webserver and post the data from the DHT11 to the webserver using the SIM808 module?

Both the SIM808 and DHT11 is connected to an Arduino Uno board.

I'm a little fuzzy on what AT commands does this...I have gone through several videos and the datasheet but still can't really understand how i can accomplish this.

Any help on this matter would be very much appreciated.

Start with the example that comes with the library you are using. Where the data for the page comes from is irrelevant.

Both is?
