如何从某个用户的数据库表中获取最新条目

Question

I have a table that displays information on users in a database:

$query = "SELECT reviews2_users.id AS IDUSER,
                            signature,
                            user,
                            email,
                            address,
                            COUNT(reviews2_reviews.id) AS COUNTER
            FROM reviews2_users LEFT JOIN reviews2_reviews ON (reviews2_users.id = reviews2_reviews.id_user)
            GROUP BY reviews2_users.id
            ORDER BY COUNTER DESC";

For every user in the table I'd like to show the date of the LATEST entry that they've made into the database.

I tried this but it doesn't work (and I'm not very good with databse/mysql):

$query = "SELECT reviews2_users.id AS IDUSER,
                            signature,
                            user,
                            email,
                            address,
                            COUNT(reviews2_reviews.id) AS COUNTER
            FROM reviews2_users LEFT JOIN reviews2_reviews ON (reviews2_users.id = reviews2_reviews.id_user)
                            AND LEFT JOIN reviews2_reviews ON max(reviews2_reviews.date)
            GROUP BY reviews2_users.id
            ORDER BY COUNTER DESC";

Could somebody help me out on this? Thank you

Please add MAX(date) to first query:

$query = "
SELECT reviews2_users.id AS IDUSER
     , signature
     , user
     , email
     , address
     , COUNT(reviews2_reviews.id) AS COUNTER
     , MAX(reviews2_reviews.date) as date
  FROM reviews2_users 
  LEFT 
  JOIN reviews2_reviews 
    ON (reviews2_users.id = reviews2_reviews.id_user)
 GROUP 
    BY reviews2_users.id
 ORDER 
    BY COUNTER DESC
";
