PHP array merge to subarray with keys - php

Question

I have a problem with merging array's. I'll try array merge and combine but nothing is working.
First array
Array (
[type1] => Array (
[userid] => Array (
[0] => 35
[1] => 37
)
[from] => Array (
[0] => 07-06-2017
[1] => 09-06-2017
)
[till] => Array (
[0] => 07-07-2017
[1] => 09-07-2017
)
)
[type3] => Array (
[userid] => Array (
[0] => 13
)
[from] => Array (
[0] => 10-06-2017
)
[till] => Array (
[0] => 10-07-2017
)
)
)
Second array
The second array is filled with room details, but the assigned users are not added yet.
Array (
[type1] => Array (
[m2] =>
[price] =>
[rooms] => 1
[extra] =>
[rented_to] => Array
(
[0] => Array
(
[userid] =>
[from] =>
[till] =>
)
)
)
[type3] => Array
(
[m2] =>
[price] =>
[rooms] => 1
[extra] =>
[rented_to] => Array
(
[0] => Array
(
[userid] =>
[from] =>
[till] =>
)
)
)
)
I'll will put these arrays together to one array, so that the data is insert into the "rented_to" section. How can I get this array into an another array like this:
Array (
[type1] => Array (
[m2] =>
[price] =>
[rooms] => 1
[extra] =>
[rented_to] => Array
(
[0] => Array
(
[userid] => 35
[from] => 07-06-2017
[till] => 07-07-2017
)
[1] => Array
(
[userid] => 37
[from] => 09-06-2017
[till] => 09-07-2017
)
)
)
[type3] => Array
(
[m2] =>
[price] =>
[rooms] => 1
[extra] =>
[rented_to] => Array
(
[0] => Array
(
[userid] => 13
[from] => 10-06-2017
[till] => 10-07-2017
)
)
)
)
The code
$manager_add_new_room_rented_to is an array that contains the value of the first array in my example.
$manager_add_new_room_type_desc = $_POST['manager_add_new_room_type_desc'];
$manager_add_new_room_type_m2 = $_POST['manager_add_new_room_type_m2'];
$manager_add_new_room_type_rent_price = $_POST['manager_add_new_room_type_rent_price'];
$manager_add_new_room_type_rooms = $_POST['manager_add_new_room_type_rooms'];
$manager_add_new_room_type_extra = $_POST['manager_add_new_room_type_extra'];
$manager_add_new_room_rented_to = $_POST['manager_add_new_room_rented_to'];
$add_new_room_information = array();
foreach ( $manager_add_new_room_type_desc as $key => $room_type ) :
$add_new_room_information[$room_type] = array(
'm2' => $manager_add_new_room_type_m2[$key],
'price' => $manager_add_new_room_type_rent_price[$key],
'rooms' => $manager_add_new_room_type_rooms[$key],
'extra' => $manager_add_new_room_type_extra[$key],
'rented_to' => array(
array(
'userid' => '',
'from' => '',
'till' => ''
)
)
);
endforeach;

Answer 1

Loop through $manager_add_new_room_rented_to[$room_type] and create the new array that you want.
foreach ( $manager_add_new_room_type_desc as $key => $room_type ) :
$renters = $manager_add_new_room_rented_to[$room_type];
$rented_to = array();
foreach ($renters['userid'] as $index => $userid) :
$rented_to[] = array('userid' => $userid, 'from' => $renters['from'][$index], 'to' => $renters['to'][$index]);
endforeach;
$add_new_room_information[$room_type] = array(
'm2' => $manager_add_new_room_type_m2[$key],
'price' => $manager_add_new_room_type_rent_price[$key],
'rooms' => $manager_add_new_room_type_rooms[$key],
'extra' => $manager_add_new_room_type_extra[$key],
'rented_to' => $rented_to
)
);
endforeach;
