Append an indexed 2d array as new associative element to an associative array

I need to restructure an array so that indexed rows of data are pushed into a new associative element called records.

Input array:

array (
  'code' => 200,
  'message' => 'OK',
  0 => 
  array (
    'title' => 'Green peppercorn and lemongrass coconut broth',
    'media' => '/posts/images/84709.jpg',
  ),
  1 => 
  array (
    'title' => 'Green peppercorn and lemongrass coconut broth',
    'media' => '/posts/images/84709.jpg',
  ),
)

Desired result:

array (
  'code' => 200,
  'message' => 'OK',
  'records' => [
    array (
      'title' => 'Green peppercorn and lemongrass coconut broth',
      'media' => '/posts/images/84709.jpg',
    ),
    array (
      'title' => 'Green peppercorn and lemongrass coconut broth',
      'media' => '/posts/images/84709.jpg',
    ),
  ),
)

It used to be two arrays; I merged with array_merge($message, $records);

You don't need to loop over the whole payload.

If you know that there are two elements at the start of the array to ignore (and it looks like a predictable format to me), just splice the remaining elements from the array, then re-append the data to the original array under the key records. Demo

$array['records'] = array_splice($array, 2);

But actually, if you are saying

It used to be two arrays; I merged with array_merge($message, $records);

And your input arrays are:

$message = ['code' => 200, 'message' => 'OK'];
$records = [
    [
        'title' => 'Green peppercorn and lemongrass coconut broth',
        'media' => '/posts/images/84709.jpg',
    ],
    [
        'title' => 'Green peppercorn and lemongrass coconut broth',
        'media' => '/posts/images/84709.jpg',
    ],
];

Then all you need to do is declare a new element containing the records payload. Demo

$message['records'] = $records;

Or use the union operator (or union assignment operator) with a temporary associative array: Demo

$message += ['records' => $records];

or Demo

$message += compact('records');

If you want a short code (one string , two with $result declaration)

$json = '{"code":200,"message":"OK","0":{"title":"Green peppercorn and lemongrass coconut broth","media":"\/posts\/images\/84709.jpg"},"1":{"title":"Green peppercorn and lemongrass coconut broth","media":"\/posts\/images\/84709.jpg"}}';
$result = [];
foreach(json_decode($json,true) as $k=>$v) if(is_array($v)){$result["records"][]=$v;} else {$result[$k]=$v;};

Make sure to change $json with your json

result (pretty_printed):

{
    "code": 200,
    "message": "OK",
    "records": [
        {
            "title": "Green peppercorn and lemongrass coconut broth",
            "media": "\/posts\/images\/84709.jpg"
        },
        {
            "title": "Green peppercorn and lemongrass coconut broth",
            "media": "\/posts\/images\/84709.jpg"
        }
    ]
}

If you want to continue with your json response then you can create a new array as like, but this example is only work for your json which you mentioned in your question:

<?php
$array = json_decode('{"code":200,"message":"OK","0":{"title":"Green peppercorn and lemongrass coconut broth","media":"\/posts\/images\/84709.jpg"},"1":{"title":"Green peppercorn and lemongrass coconut broth","media":"\/posts\/images\/84709.jpg"}}
',true);

$newArray = array(); // initialize new array 
foreach ($array as $key => $value) {
    if(is_array($value))    { // if having array
        $newArray['records'][] = $value;
    }
    else{
        $newArray[$key] = $value;
    }
}
echo json_encode($newArray);
?>

Result:

{"code":200,"message":"OK","records":[{"title":"Green peppercorn and lemongrass coconut broth","media":"\/posts\/images\/84709.jpg"},{"title":"Green peppercorn and lemongrass coconut broth","media":"\/posts\/images\/84709.jpg"}]} Second, if you are mergin two array `array_merge($message, $records);`

Second Solution (recommended), if you are combining two array and wants to add a new index records then you can also modify by adding a records index as:

$newArray = $message;
$newArray['records'] = $records;
echo json_encode($newArray);
