在php中读取JSON格式的文件

Question

I'm very new at JSON, I'm trying to read one parameter of this file using php:

stdClass Object
(
    [status] => OK
    [results] => Array
        (
            [0] => stdClass Object
                (
                    [types] => Array
                        (
                            [0] => route
                        )

                    [formatted_address] => Foro Umberto I, 90133 Palermo, Italy
                    [address_components] => Array
                        (
                            [0] => stdClass Object
                                (
                                    [long_name] => Foro Umberto I
                                    [short_name] => SS113
                                    [types] => Array
                                        (
                                            [0] => route
                                        )

                                )

This is only a part, anyway, i need to echo the formatted_address using php, but i can get it, this is part of my code:

$address = json_decode($curlData);
echo($address -> {'formatted_address'});

Thanks for any help!

Answer 1

$data = json_decode($curlData);
$result = $data->results[0];
$address = $result->formatted_address;

Answer 2

I don't think you need the brackets or the quotes:

echo $address -> formatted_address;

Also, for what it's worth, when you use json_decode you can also have it return an array instead of an object by telling it true in the second argument:

$address = json_decode($whatever, true);
echo $address['formatted_address'];

...If that helps you any.

Answer 3

解码json后，您只有一个普通的旧PHP对象，因此您可以执行以下操作：

$address->formatted_address
