Magento Api request foreach error

Question

I am trying to get attribute option Ids for a sku using this below api call.

http://localhost/rest/V1/configurable-products/sh8/options/all

I used this curl request:

$curl = curl_init();

curl_setopt_array($curl, array(
  CURLOPT_URL => "http://localhost/rest/V1/configurable-products/sh8/options/all",
  CURLOPT_RETURNTRANSFER => true,
  CURLOPT_ENCODING => "",
  CURLOPT_MAXREDIRS => 10,
  CURLOPT_TIMEOUT => 30,
  CURLOPT_HTTP_VERSION => CURL_HTTP_VERSION_1_1,
  CURLOPT_CUSTOMREQUEST => "GET",
  CURLOPT_HTTPHEADER => array(
    "cache-control: no-cache",
    "postman-token: f1457b50-7a5e-4f08-d6ee-8e3b0aad21bd"
  ),
));

$response = curl_exec($curl);
$err = curl_error($curl);

curl_close($curl);

if ($err) {
  echo "cURL Error #:" . $err;
} else {

   echo $response;
    }

I got this below response:

[
    {
        "id": 26,
        "attribute_id": "145",
        "label": "size",
        "position": 1,
        "values": [
            {
                "value_index": 25
            },
            {
                "value_index": 27
            },
            {
                "value_index": 28
            },
            {
                "value_index": 29
            }
        ],
        "product_id": 161
    },
    {
        "id": 27,
        "attribute_id": "146",
        "label": "color",
        "position": 0,
        "values": [
            {
                "value_index": 30
            },
            {
                "value_index": 31
            },
            {
                "value_index": 32
            }
        ],
        "product_id": 161
    }
]

But when I try to access this in foreach like

 foreach ($response as  $value) {
       var_dump($value);
    }

I get this below error:

Exception #0 (Exception): Warning: Invalid argument supplied for foreach()

It gives the error because response is in json you need to do

$response = json_decode($response);

before passing to foreach

I hope this will help

Your $response result is in JSON format so you have to decode it in order to access data.

$data = json_decode($response);

And in your foreach do like this to get the value of the key attribute_id:

foreach ($data as $value){
    echo "<br/>";
    echo $value['attribute_id'];
}

Note: you can change the key to what you need to get
