Create new array from another - php

Question

i have an array:
Array
(
[users] => Array
(
[101] => Array
(
[odata] => Array
(
[0] => 2
[1] => 1
[2] => 1
[3] => 1
)
)
[200] => Array
(
[odata] => Array
(
[0] => 2
[1] => 1
[2] => 1
[3] => 0
)
)
)
[rjad] => Array
(
[2] => Array
(
[0] => red
[1] => blue
[2] => green
)
)
)
in this array [rjad] key = [odata] key, and [odata] value = second key in [rjad].
What i want is to create new array from old one with user ids values in second array:
like this:
[rjad] => Array
(
[2] => Array
(
[0] => red
[1] => Array
(
[blue] => Array
(
[0] => 101
[1] => 200
)
[2] => green
)
)
Struggling already 3 hours with no success. Any ideas how to get it are very wellcome.

Answer 1

I'd seriously rethink your structure, but here's a working (if ugly) solution
foreach ($users as $userId => $user) {
foreach ($user['odata'] as $key => $value) {
if (isset($rjad[$key][$value])) {
if (!is_array($rjad[$key][$value])) {
$colour = $rjad[$key][$value];
$rjad[$key][$value] = array();
$rjad[$key][$value][$colour] = array();
} else {
reset($rjad[$key][$value]);
$colour = key($rjad[$key][$value]);
}
$rjad[$key][$value][$colour][] = $userId;
}
}
}

Based on comments seems you may want a separate array, which is easily solved
// copy the array and act on it instead of directly on $rjad
$result = $rjad;
foreach ($users as $userId => $user) {
foreach ($user['odata'] as $key => $value) {
if (isset($result[$key][$value])) {
if (!is_array($result[$key][$value])) {
$colour = $result[$key][$value];
$result[$key][$value] = array();
$result[$key][$value][$colour] = array();
} else {
reset($result[$key][$value]);
$colour = key($result[$key][$value]);
}
$result[$key][$value][$colour][] = $userId;
}
}
}

Answer 2

Your question isn't entirely clear - what is the relationship between rjad...blue and those user accounts from the other array? Is item 0 in the odata arrays the default colour?
