In my project i have elements stored in a database table. I want to allow the users of my website to add them to favorites.
I am not sure how to start with this one.
What is a good way to create favorites functionality?

you can create a new table named favorites and add 2 fields, one for the username and other for the element id so you may have one user with many elements
Chema Castellanos answer should fix your issue, but instead of username I would use the user id against the element id. User numebrs where possible because they're a lot faster to index!
If you have a user with the id of 1 and an element of the id of 1, you would create a new row in your "favorites" table with values of 1 & 1. This would create the join between the element and the user.
The relationship is many-to-many because an element can be favorited by many users and a user can favorite many elements.
I think it's also good to add a table id for the 'favorite', giving you three columns in your joining table.
