Notice: Undefined offset: 0 in

Question

I am getting this PHP error, what does it mean?

Notice: Undefined offset: 0 in 
C:\\xampp\\htdocs\\mywebsite\\reddit_vote_tut\\src\\votes.php on line 41
         


        

Answer 1

getAllVotes() isn't returning an array with the indexes 0 or 1. Make sure it's returning the data you want by calling var_dump() on the result.
