Question

I have an array full of dynamic <select> field options, that I would like to be split into separate arrays based on a certain value within each “loop”.

Basically, I’d like two arrays: one with the data associated with [subfirmdetailtype_id] = 14, and one with [subfirmdetailtype] = 25.

Any help would be appreciated!

Array
(
    [0] => Array
        (
            [Subfirmdetailoption] => Array
                (
                    [option] => Open
                    [subfirmdetailtype_id] => 14
                )

        )

    [1] => Array
        (
            [Subfirmdetailoption] => Array
                (
                    [option] => Closed
                    [subfirmdetailtype_id] => 14
                )

        )

    [2] => Array
        (
            [Subfirmdetailoption] => Array
                (
                    [option] => Large Growth
                    [subfirmdetailtype_id] => 25
                )

        )

    [3] => Array
        (
            [Subfirmdetailoption] => Array

                    [subfirmdetailtype_id] => 25

Answer 1

This will group arrays the way you want:

$new_array = array();

foreach ($your_array as $array) {
  $new_array['subfirmdetailtype_id'][
     $array['Subfirmdetailoption']['subfirmdetailtype_id']
  ][] = $array['Subfirmdetailoption'];
}

Later you can access groups like this:

$new_array['subfirmdetailtype_id'][14];
$new_array['subfirmdetailtype_id'][15];

Or loop through these grouped arrays.
