I want to press a button on my website, that will switch one of the GPIO pins on my raspberry pi on/off. I'm not even sure if this is possible. I was thinking of having some sort of script run on my computer/RPi that listens for a certain message. Preferably i'd solve all this in Python and PHP because i'm fairly familiar with these languages, and my personal website only has PHP. Sorry if this is a noob question, im pretty new to programming but i'd like to try all this. Seems like a challenge!
