Edit an array with new values in PHP - php

Question

I have this array:
Array
(
[datas] => Array
(
[General] => Array
(
[0] => Array
(
[id] => logo
[size] => 10
)
)
[Rooms] => Array
(
[0] => Array
(
[id] => room_1
[size] => 8
)
[1] => Array
(
[id] => room_2
[size] => 8
)
[2] => Array
(
[id] => room_3
[size] => 8
)
)
)
)
I need to update it when I receive some info like this:
$key = 'room_3';
$toChange = '9';
So in my array, I want to change the size of room_3.
I will always edit the same element (i.e. size).
What I tried:
// Function to communicate with the array
getDatas($array, 'room_3', '9');
function getDatas($datas, $got, $to_find) {
foreach ($datas as $d) {
if (array_search($got, $d)) {
if (in_array($to_find, array_keys($d))) {
return trim($d[$to_find]);
}
}
}
}
But it does not work...
Could you please help me ?
Thanks.

Answer 1

function getDatas($datas, $got, $to_find) {
foreach($datas['datas'] as $key => $rows) {
foreach($rows as $number => $row) {
if($row['id'] == $got) {
// u can return new value
return $row['size'];
// or you can change it and return update array
$datas['dates'][$key][$number]['size'] = $to_find; // it should be sth like $new value
return $datas;
}
}
}
}

Answer 2

function changeRoomSize (&$datas, $roomID, $newSize ){
//assuming that you have provided valid data in $datas array
foreach($datas['datas']['Rooms'] as &$room){
if($room['id'] == $roomID){
$room['size'] = $newSize;
break;//you can add break to stop looping after the room size is changed
}
}
}
//--- > define here your array with data
//and then call this function
changeRoomSize($data,"room_3",9);
//print the results
var_dump($data);

It's a 3-dimensional array, if you want to change the value, do like this:
$key = 'room_3';
$toChange = '9';
$array['datas'] = getRooms($array['datas'], $key, $toChange);
function getRooms($rooms, $key, $toChange) {
foreach($rooms as $k1=>$v1) foreach ($v1 as $k2=>$v2) {
if ($v2['id'] == $key)) {
$rooms[$k1][$k2]['size'] = $toChange;
}
}
return $rooms;
}
print_r($array);
