php - Select data from the most recent row, with a particular ID -

-

i have database looks this:

id   |   account_id   |       date_time       |   followers -------------------------------------------------------------- 1    |         1813   |  2014-11-16 09:31:52  |        1527 -------------------------------------------------------------- 2    |         1826   |  2014-11-16 09:31:52  |         900 -------------------------------------------------------------- 3    |         1854   |  2014-11-16 09:32:25  |       15342 -------------------------------------------------------------- 4    |         1813   |  2014-11-16 16:31:52  |        1539 -------------------------------------------------------------- 5    |         1826   |  2014-11-16 16:31:52  |         905 -------------------------------------------------------------- 6    |         1854   |  2014-11-16 15:32:25  |       15349 --------------------------------------------------------------

the database repeats same sort of entries twice-daily. each day there 2 new entries account_id 1813, 1826, 1854 etc.

how can select number of followers last entry particular account_id?

so using data above, include account_id 1813 , follower_count 1539.

i'm using php , mysqli if helps. 

select followers your_table account_id = 1813 order date_time desc limit 1
