You can use GROUP_CONCAT to get a similar resultset :

SELECT GROUP_CONCAT( user_id ) FROM table GROUP BY user_id

Otherwise if you want to create a new column for each row in the result set you can go with a CASE, but the values or the ranges of values must be hard coded :

SELECT CASE WHEN user_id = 108 THEN user_id ELSE 0 END AS m1, CASE WHEN user_id = 183 THEN user_id ELSE 0 END AS m2, ...

Or by ranges :

SELECT CASE WHEN user_id > 100  AND user_id < 150 THEN GROUP_CONCAT(user_id) ELSE 0 END AS m1, CASE WHEN user_id > 150 AND user_id < 200 THEN GROUP_CONCAT(user_id) ELSE 0 END AS m2, ...
