Look at W3Schools. Like this: https://www.google.com/search?q=w3schools+php+mysql
I work in an office and I want to impress the bosses. I want to build a platform to display the status of various tasks assigned to employees. I know there are products that you can buy but I also know that this can be done relatively easily. I want to be able to go to a place, browser I'm assuming but that's how little I know, and update information that will then be sent to a display in another room. I think this can be done using PHP and MySql but I'm just regurgitating the few key words that I've stumbled upon. Can anyone please tell me where I need to start so I can learn how to build everything from scratch? Will I need a Pi?
