How to extract a key from a subarray?

Question

PHP

I have an array like:

$arr['data'][0]['ID']
$arr['data'][0]['static']
$arr['data'][1]['ID']
$arr['data'][1]['static']

etc.
How to make an array of the form:
$arr['data']['ID']['static'] from it?

Answer 1

On the advice of Vladislav Kopylov , I did through FOREACH:

foreach ($arr['data'] as $mm) {
  $copy_arr[$mm['tank_id']] = $mm['all']; // "all" = "static"
}

Answer 2

$arr['data'] = $arr['data'][0]; only index 1 in the third line is confusing.
In general, it looks like a series of unsuccessful programming decisions. Most likely, something somewhere needs to be simplified.
