The `Arr::only()` helper function in Laravel provides a convenient way to extract specific keys from an array, creating a new array with only the desired keys and their corresponding values. However, it's important to note that the `Arr::only()` function does not allow for renaming the keys of the array during the extraction process. This functionality is not built into the `Arr::only()` function.
To achieve the desired result of renaming keys while extracting specific values from an array, you can utilize a combination of other Laravel helper functions and PHP's native array manipulation capabilities:
```html // Original array $array = [ 'old_key_1' => 'value_1', 'old_key_2' => 'value_2', 'old_key_3' => 'value_3', ]; // Create a new array with specific keys using Arr::only() $selectedKeys = ['old_key_1', 'old_key_3']; $intermediateArray = Arr::only($array, $selectedKeys); // Rename the keys using PHP's array_combine() function $newKeys = ['new_key_1', 'new_key_3']; $renamedArray = array_combine($newKeys, $intermediateArray); // Display the renamed array print_r($renamedArray); ```In this example, we first extract the desired keys using `Arr::only()`, resulting in the `$intermediateArray`. Then, we use `array_combine()` to rename the keys of the array to the desired new keys, creating the `$renamedArray`. This approach allows you to achieve the desired result of renaming keys while extracting specific values from an array.
