Send integers to a PHP server

Hi to all,

I'm using the GPRS Shield SIM900 with Arduino in order to be able to send data over a network and it is working fine.

I have a counter device which periodically reads data in JSON format from my PHP web page and display the results on its device.

I would like to change the data displayed by my PHP web page by using Arduino.
I was thinking to use store the data sent by Arduino in a MySQL database and then use my webpage to retrieve them.

Is this the only solution?
Can you suggest me a better and faster solution, please?

Thank you!
