Array Help

I have this after submitting a form

[SelectionsSkills] => Array
(
[1] => Array
(
[13] => 4
)

[2] => Array
(
[1] => 4
)

[3] => Array
(
[9] =>
)

[4] => Array
(
[8] =>
)

[5] => Array
(
[7] => 4
)
)

)

And I need to do 2 things with this array
- where [9] => and [8] => have no value I need to remove them from the array
- where [13] => 4, [1] => 4 and [7] => 4, I need 2 values each key / value,
the numbers in brackets represent the selection_id and the value represent
the year_id they selected for that particular skill

Any ideas how I can do this?

Merry Christmas to all those still working :)
