Is there a way to store an array into mysql field? I'm creating a comment rating system so I want to store the arrays of user ids to prevent multiple votings. I'm going to create new table that holds the comment id and the array of user ids who have voted on this comment. Than I'll join comments table and this table and check whether the current user id exists in the voters array or note. If it does than the voting icons would be disabled. I think I'll prevent to use mysql query in loop in this way.
Do you happen to know any better ways?
You can always serialize the array and store that in the database.
You can then unserialize the array when needed.
