I'm trying to create a table which outputs a list of users and how many times they've logged in.

A new row in the table is created every time that someone logs in so there is multiple rows for one user.

Now, I'm trying using the following statement to pull the data out:

SELECT * FROM logins GROUP BY user ORDER BY timestamp DESC

Which is working fine but now there is a column in my HTML table which should show how many times the user has logged in. How do I go about counting the amount of rows in each group?
