I need an Arduino to send a message, to be displayed on the web, after pressing a push button, which is connected to an Arduino [or shield], without using a GSM shield.

I need to send a message just by using HTML/PHP code included in the Arduino IDE. This displayed message should contain two buttons. One button is used to turn a LED ON/OFF and the other to open a streaming video.

Can anyone help me with the Arduino code and explain how I should do that? Is there any third party device, apart from a GSM shield, that can help me to send that message?
