Select specific keys from array

[ludo1960]

Hi guys,

I am getting data from a json source:

```

$jsondata = file_get_contents($url);

 

$response = json_decode($jsondata, true)

 

echo "<pre>"; print_r(array_keys($response));; echo "</pre>";

```

and this returns:

```

Array
(
    [0] => jsonapi
    [1] => data
    [2] => links
)

```

I want  to extract data from specific key in the data array (eg 'title'):

```

    [data] => Array
        (
            [0] => Array
                (
                    [type] => recipes
                    [id] => d6cd7643-6e44-4d26-9ed9-9da7196cef12
                    [attributes] => Array
                        (
                            [internalId] => 7
                            [isPublished] => 1
                            [title] => Deep mediterranean quiche
                            [createdAt] => 2019-05-07T13:34:27+0200
                            [updatedAt] => 2019-05-07T13:34:27+0200
                            [isPromoted] => 1
                            [path] => /recipes/deep-mediterranean-quiche
                            [cookingTime] => 30
                            [difficulty] => medium
                            [ingredients] => Array
                                (
                                    [0] => For the pastry:
                                    [1] => 280g plain flour
                                    [2] => 140g butter
                                    [3] => Cold water
                                    [4] => For the filling:
                                    [5] => 1 onion
                                    [6] => 2 garlic cloves
                                    [7] => Half a courgette
                                    [8] => 450ml soya milk
                                    [9] => 500g grated parmesan
                                    [10] => 2 eggs
                                    [11] => 200g sun dried tomatoes
                                    [12] => 100g feta
                                )

                            [numberOfservings] => 8
                            [preparationTime] => 40
                            [instructions] => 

```

How do I loop through the data array and select just the 'title' and 'difficulty' for example?

Just use the index hierarchy down to the item you want

echo $array['data'][0]['attributes']['title']

Perfect, thanks Barand.
