Merge indexed arrays from POST request - php

Question

I have this array coming from post request:
$x = [
"meal" => [
"monday" => [
"breakfast" => [
0 => "type1",
1 => "type1",
],
"afternoonTea" => [
0 => "type2",
],
],
],
"number" => [
"monday" => [
"breakfast" => [
0 => "10",
1 => "9",
],
"afternoonTea" => [
0 => "1",
],
],
],
];
I am trying to merge all this into one array without using tones of foreaches.
Maybe someone more clever will know how to use iterators to achieve that.
Data from meal and number is always 1:1.
I need to convert this to something like this:
$x = [
"monday" => [
"breakfast" => [
[
'type' => "type1",
'number' => 10,
],
[
'type' => "type1",
'number' => 9
]
],
"afternoonTea" => [
[
'type' => "type2",
'number' => 1,
],
],
],
],
];

If you count 3 as being tonnes then this isn't your answer - but I can't see a way of reducing down the number of reach loops below this without getting to a game of code golf which won't be helpful.
Because you know there is a 1:1 relationship between meal and number, you can use the indexes from one to get data from the other by doing:
$result = [];
foreach($x['meal'] as $day => $list) {
foreach($list as $activity => $types) {
foreach($types as $i => $type) {
$result[$day][$activity][] = [
'type' => $type,
'value' => $x['number'][$day][$activity][$i],
];
}
}
}
The output of this will be $result will contain the array in the format you want.
