This is my first array which i get from mysql
Array
([0] => Array
(
[created_by] => 4
[count] => 1
[total] => 300
)
[1] => Array
(
[created_by] => 4
[count] => 1
[total] => 450
)
[2] => Array
(
[created_by] => 3
[count] => 1
[total] => 500
)
)
I need a output as
[0] => Array
(
[created_by] => 4
[count] => 2
[total] => 750
)
[1] => Array
(
[created_by] => 3
[count] => 1

Sum of array total based on created_by Need to group by created_by count.
