Help With Creating An Array

I want to create an array from the content provided in 3 different checkboxes. I am using WP Frontend in WordPress, to create a form that has different multiselect boxes for different categories.

For example:

**Category 1:** Tags: 45,78,97
**Category 2**: Numbers: 3,7,9
**Category 3:** Marks: 4,8,12

When Selected, I would like to create an array that would look like this:

Array
(
[tags] => Array
(
[0] => Array
(
[0] => 45
[1] => 78
[2] => 97
)
)
[numbers] => Array
(
[0] => 3
)
[marks] => Array
(
[0] => 18
)
)

Then I would like to serialize it, which would look like this:

a:3:{s:4:”tags”;a:1:{i:0;a:3:{i:0;i:45;i:1;i:78;i:2;i:97;}}s:7:”numbers”;a:1:{i:0;s:1:”3″;}s:5:”marks”;a:1:{i:0;s:1:”18″;}}

Any advice on the best way of creating this would be massively appreciated.

Thanks
