I want to add values from one array to another that are both potentially multidimensional when they have the same ID. Hard to explain so I added example.
arr1 => new structure, without full data
arr2 => old structure, with full data
Examples if you'd like to help out:
// arr1 (the correct structure/order, without the full data)
[{
"id": "24",
"children": [{
"id": "21",
"children": [{
"id": "15"
}]
}]
}]
// arr2 (full data, not in any specific order, may be nested)
[{
"id": "24",
"name": " x",
"time": "0",
"status": "0"
}, {
"id": "21",
"children": [{
"id": "15",
"name": "x",
"time": "0",
"status": "0"
}],
"name": "x",
"time": "0",
"status": "0"
}]
// arr3 (desired output for this example)
[{
"id": "24",
"children": [{
"id": "21",
"children": [{
"id": "15",
"name": "x",
"time": "0",
"status": "0"
}],
"name": "x",
"time": "0",
"status": "0"
}],
"name": " x",
"time": "0",
"status": "0"
}]
I tried this:
function merge($arr1, $arr2) {
foreach($arr1 as $key => $value){
foreach($arr2 as $value2) {
if($value['id'] === $value2['id']){
$arr1[$key]['name'] = $value2['name'];
$arr1[$key]['time'] = $value2['time'];
$arr1[$key]['status'] = $value2['status'];
if (is_array($value)) {
$arr1[$key]['children'] = merge($arr1, $arr2);
}
}
}
}
return $arr1;
}
to combine them, but I can't figure out how to handle the nesting correctly. I have tried a lot of other things as well like using array_merge_recursive() but it doesn't work because I want to merge based on ID value. Any help on getting me on track would be awesome thanks.
Current output for example:
[{
"id": "24",
"children": [{
"id": "21",
"children": [{
"id": "15"
}]
}],
"name": " x",
"time": "0",
"status": "0"
}]
Desired output for example:
[{
"id": "24",
"children": [{
"id": "21",
"children": [{
"id": "15",
"name": "x",
"time": "0",
"status": "0"
}],
"name": "x",
"time": "0",
"status": "0"
}],
"name": " x",
"time": "0",
"status": "0"
}]
