If you're doing this using PDO then you need to modify the query to all be within the single statement in order to get it to work properly. See PHP/PDO/MySQL: Convert Multiple Queries Into Single Query

SELECT t.*, (@count := @count + 1) as rank
FROM table t 
CROSS JOIN (SELECT @count := 0) CONST
ORDER BY t.popularity;
