Replace associative element in each row with the associative grandchild of the unwanted parent element

I need to restructure a multidimensional array in a Drupal application.

enter image description here

Here is full image:

field_new => [...] has to become 'value' => '11111'

I recommend directly modifying the input array by using array destructuring syntax to isolate the data subarray as a reference variable, then declare the value to be the deepest scalar value of field_new.

Code: (Demo)

foreach ($array as ['data' => &$data]) { 
    $data['value'] = $data['field_new']['und'][0]['value'];
    unset($data['field_new']);
}
var_export($array);

Your Input Array:

...
0{
    data{
        nid => 1
        vid => 1
        type => article
        field_new{
            und{
                0{
                    value => 11111
                }
            }
        }
    }
}
1{
    data{
        nid => 2
        vid => 2
        type => article
        field_new{
            und{
                0{
                    value => 33333
                }
            }
        }
    }
}

Your desired array:

...
0{
    data{
        nid => 1
        vid => 1
        type => article
        value => 11111
    }
}
1{
    data{
        nid => 2
        vid => 2
        type => article
        value => 33333
    }
}

Unset (http://php.net/manual/en/function.unset.php) is our friend.

unset() destroys the specified variables.

Use this code:

<?php

$loop_count = count($input_arr);
for($i=0;$i<loop_count;$i++){
    //copy the value to the desired place
    $input_arr[$i]["data"]["value"] = $input_arr[$i]["data"]["field_new"]["und"][0]["value"];

    //delete the unwanted portion
    unset($input_arr[$i]["data"]["field_new"]);
} // for loops ENDS

?>

Assumptions:

  • Your base/parent array is numerically indexed.
  • In each array, field_new is at same level.

Please add the code you are using you to produce/get this array, and we could provide you more specific answers.
