Question

Using an application’s API, I’m able to retrieve data as a JSON and put it in an array.

$json = file_get_contents($url);
$obj = json_decode($json);
print_r($obj);

When I print the array, I see:

stdClass Object(
    [metadataList] = > stdClass Object(
        [metadata] = > Array(
                [0] = > stdClass Object([metadataName] = > category [metadataValue] = > RECIPES)
                [1] = > stdClass Object([metadataName] = > title [metadataValue] = > Easy Sugar Cookies)
            )
        )
)

I need to set a variable equal to the title metadata value (“Easy Sugar Cookies”), but I’m having some trouble.

Here’s where I am so far, but I’m not having any luck figuring out how to specify the specific metadataValue key, since there is more than one in the array.

$title = array_search('description',($obj->{'metadataList'}->{'metadata'}));

I think this is you have want…

$obj = json_decode($json, true);
$value = '';
  foreach($obj['metadataList']['metaData'] as $metadata) {
  if($metadata['metadataName'] === 'someName') {
    $value = $metadata['metadataValue'];
    break;
  }
   continue ;

}
