Count on multidimensional array

Posted on 16th Feb 2014 07:03 pm by admin

Hi, i got an array as below:

Array
(
=> Array
(
[2009-12-08] => 1
)
[1] => Array
(
[2009-12-07] => 1
)
[2] => Array
(
[2009-12-04] => 1
)
[3] => Array
(
[2009-12-03] => 10
)
[4] => Array
(
[2009-12-02] => 10
)
[5] => Array
(
[2009-12-01] => 10
)
[6] => Array
(
[2009-12-10] => 6
)
[7] => Array
(
[2009-12-08] => 5
)
[8] => Array
(
[2009-12-07] => 10
)
[9] => Array
(
[2009-12-04] => 1
)
[10] => Array
(
[2009-12-02] => 3
)
[11] => Array
(
[2009-12-01] => 10
)
)

i would like to do a sum on each date, and generate the below array:

Array
(
=> Array
(
[2009-12-10] => 6
)
[1] => Array
(
[2009-12-08] => 6
)

[2] => Array
(
[2009-12-07] => 11
)

[3] => Array
(
[2009-12-04] => 2
)

[4] => Array
(
[2009-12-03] => 10
)

[6] => Array
(
[2009-12-02] => 13
)

[6] => Array
(
[2009-12-01] => 20
)
)

Any idea? Thanks
