I was wondering if there is any way to set unique values to each cookie. I want to use these cookies on my website to see if the visitor has already visited my website once, but without asking any information from them. This way I want to store this unique value in my database each time someone opens my website, and I will be able to see if there have been - for example - 20 different visitors in the past month, or if the same person has visited my website 20 times. All my code is already written and working, I only need a way to set a different unique value to each cookie I set.

I am creating a table using phpMyAdmin. I would appreciate if someone would explain: In the collation, I am selecting utf8_general_ci. Is this OK? For indexing, when should I use ''unique and when would I use 'index'?
