• ram
• mouse
• keyboard
• monitor

Answer 1

PHP is a server-side language. You are not able to detect computer specs. However, you can use JavaScript to detect some basic screen related things like resolution, pixel depth, colors etc.

PHP is able to detect network information and some settings.

It sounds like an exploit into users' privacy. There won't be any universal way to do that but there may be ways for certain combinations of operating systems, browsers and plugins. You could certainly use a browser extension users could install in their computers, or even a binary executable that would send out the results that could later be accessed on your website.

In JS you can get some of this information:

Computer Memory (only supported in chrome):

console.log('Memory', navigator.deviceMemory);

Computer Cores:

console.log('Cores', navigator.hardwareConcurrency);

Connection Speed:

console.log('Connection', navigator.connection);
