推荐答案
访问它的另一种错误是:
Another twist on how inerte did it would be to access it like:
$json_object = '{"communications":
{"communication":
[{"@array":"true","@id":"23101384","@uri":"xyz/v1/Communications/1111","household":
{"@id":"111111","@uri":"xyz/v1/Households/5465465"},

$json_decoded = json_decode($json_object);
