Get elements with same key but different value in two PHP arrays

So i get info from a JSON file and i get one array called "items" and pass it to this array in PHP:

"items": [
{
  "id": "2",
  "parent": null,
  "itemType": 0,
  "title": "Manuel Perez",
  "description": "Chief Executive Officer (CEO)",
  "phone": "(491) 183-55-45",
  "email": "[email protected]",
  "photo": "",
  "image": "demo/images/photos/m.png",
  "href": "showdetails.php?recordid=2",
  "isVisible": true
}

Then i have to compare this with another that can contain more or less items, but i can take those elements that change the size of the array. But when i want to get the difference when the size is the same and a value of a key is different when i cant make it work.

If in the second array in the position 2 the value of "itemType" change to 1 i want to get somenthing like this:

Array[2] - > "itemType": 1

And so that way i can know if something changed.

Suppose you have two arrays $items1 and $items2:

$items1 = [
    "id" => "2",
    "itemType" => 0,
];

$items2 = [
    "parent" => null,
    "itemType" => 1,
];

To get the things that are added or modified in $items2 compared to $item1, you can use:

array_diff_assoc($items2, $items1) // displays ['parent' => null, 'itemType' => 1]

To get the things that are added or modified in $items1 compared to $item2, you can use:

array_diff_assoc($items1, $items2) // displays ['id' => "2", 'itemType' => 0]

If you want both, you can combine these two arrays and use them as you wish.

  1. First of all covert your JSON data into Array and take items form both into $jsonArray1 and $jsonArray2 respectively.

  2. Now sort your both array by key like this ksort($jsonArray1); ksort($jsonArray2);

  3. Now take difference of both array $diffData = array_diff_assoc($jsonArray1, $jsonArray2);

Output: $diffData is your output, hope this will help!!
