PHP：从非本机数组返回值？

Question

I have a function that's sending a query and receiving an array in the following format:

{
    "id1" : 312293.23451244,
    "id2" : 6.03937464,
    "id3" : 1
}

Using PHP, how could I return the value for "id1"?

Thanks!

Answer 1

$data = '{
    "id1" : 312293.23451244,
    "id2" : 6.03937464,
    "id3" : 1
}';
$json = json_decode($data, true);
return  $json['id1'];
