Merge nested json values in php
Get the solution ↓↓↓
In PHP, I am struggling to merge two json objects ($old and$new ) with nested values:
echo "OLD: ".$old;
echo "NEW: ".$new;
Result:
{-code-4}
Expected result I needed:
{"4":{"deu":1, "eng":2, "fra":1}}
Attempts:
Triedjson_decode() andarray_merge() but got a json result with missing key4
I got these kind of results:
{{"deu":1, "eng":2, "fra":1}}
//or
[{"deu":1, "eng":1, "fra":1},{"deu":1, "eng":2}]
As you can see the key4 is missing from the result

Solution:
You need to useforeach() as well along withjson_decode() andarray_merge()
<?php
$old = '{"4":{"deu":1, "eng":1, "fra":1}}';
$new = '{"4":{"deu":1, "eng":2}}';
$oldArray = json_decode($old,true);
$newArray = json_decode($new,true);
$finalArray =[];
foreach($oldArray as $key=>$value){
$finalArray[$key] = array_merge($value,$newArray[$key]);
}
print_r($finalArray);
echo json_encode($finalArray);
