Use LIMIT

$sql_time = "SELECT date FROM tb_player_activity 
              WHERE user_id='$data[1]' 
              GROUP BY date DESC 
              LIMIT 3"; 

MySQL LIMIT Clause. In MySQL the LIMIT clause is used with the SELECT statement to restrict the number of rows in the result set. The Limit Clause accepts one or two arguments which are offset and count.The value of both the parameters can be zero or positive integers.
