Sort the Multi Dimensional array in key sequence - php

Question

Basically, I am building html form inputs that have dynamic inputs For example In below example if user want to increase the unit_type then user can add the new input from front end and send it to store
Note: If user will add the unit_type then all others keys will automatically added. Like if user try to increase the unit_type then unit_address and all other inputs increase accordingly.
Right Now I have the array like this
array:7 [
"unit_type" => array:2 [
0 => null
1 => null
]
"unit_address" => array:2 [
0 => null
1 => null
]
"unit_phone" => array:2 [
0 => null
1 => null
]
"fax" => array:2 [
0 => null
1 => null
]
"installed_capacity" => array:2 [
0 => null
1 => null
]
"production_capacity" => array:2 [
0 => null
1 => null
]
"unit_email" => array:2 [
0 => null
1 => null
]
]
Expected Result
[
[
//Here all keys contain the first values of all arrays
'unit_type'=>'first_value',
'unit_address'=>'first_value',
'unit_phone'=>'first_value',
'fax'=>'first_value',
'installed_capacity'=>'first_value',
'production_capacity'=>'first_value',
'unit_email'=>'first_value'
],
[
//Here all keys contain the second values of all arrays
'unit_type'=>'second_value',
'unit_address'=>'second_value',
'unit_phone'=>'second_value',
'fax'=>'second_value',
'installed_capacity'=>'second_value',
'production_capacity'=>'second_value',
'unit_email'=>'second_value'
]
]

Loop through the existing return data and build the new array like so:
$input_array = []; //your data received from the front end
$return_array = []; //structured data return
foreach($input_array as $field => $fieldData){
foreach ($fieldData as $key => $data){
$return_array[$key][$field] = $data;
}
}
