Sorry, I was under the impression that you had some knowledge of database operation.
Okay, you see in this image:
towards the bottom where he has the parameter $sql="SELECT * FROM scores ORDER BY score DESC LIMIT 10"
You simply need to remove the "LIMIT 10" and it will return all of the scores in the database ordered by score descending.
That is what that select statement is asking for:
SELECT (tells the database to get data)
* (tells it to return all data)
FROM scores (from the "scores" table)
ORDER BY score (order the data lexicographically by score)
DESC (in a descending order from highest to lowest)
LIMIT 10 (only return the top 10 scores)
How can I turn it to use 3 columns instead of 3.
Also this question makes no sense.
