Question

I’m developing an visits counter and I’d like to increase a number depending on the browser and the operating system.

For example:

Firefox     Mac OS X 

Safari      Mac OS X 

Firefox     Mac OS X

Firefox     Linux

Then the website would display

Safari on Mac OS X 1 visit

Firefox on Mac OS X 2 visits

Firefox on Linux 1 visit

There are a lot of browsers and operating systems combinations, then I’d like to use an algorithm that will calculate that easily. The data is retrieved from a MYSQL database. Does anyone knows a good way to do it?

Answer 1

SELECT browser, os, COUNT(*) as c FROM table GROUP BY browser, os;
