Hello,

I've got a database with video ids and N keywords for each video. I made a table with 1 video ID and 1 keyword ID in each row.

What's the easiest way to order keywords by frequency? I mean to extract the number of times a keyword is used and order them.

Is it possible to do that with sql or do I need to use php arrays?

Thanks
