JSON只在解码时返回第一个字符？

My JSON:

{"data":{"addresses":{"bitcoincash":"qzx3k8cq2e66k4glnt2derr5mppzc6xmvuxgsyp778","bitcoin":"1GjKuo1Q9sw8NytE31J5RPnVpYpEzp47hu","ethereum":"0xd7410e84e9c336937637e3cb472ad112c258ede3","litecoin":"LiQCBwuvW4RVuAg2dBNzS4fkviDwi8EBKa"},"code":"PGVD745Y","created_at":"2018-08-18T04:26:23Z","description":"dddd","expires_at":"2018-08-18T05:26:23Z","hosted_url":"https://commerce.coinbase.com/charges/example","id":"ddd","metadata":{"customer_id":"IuYBD5X7ylEV6g0xyTWi","name":"Guest@localhost.com"},"name":"ddd","payments":[],"pricing":{"local":{"amount":"19.85","currency":"USD"},"ethereum":{"amount":"0.063584000","currency":"ETH"},"bitcoin":{"amount":"0.00303719","currency":"BTC"},"bitcoincash":{"amount":"0.03345637","currency":"BCH"},"litecoin":{"amount":"0.32861518","currency":"LTC"}},"pricing_type":"fixed_price","resource":"charge","timeline":[{"status":"NEW","time":"2018-08-18T04:26:23Z"}]}}

My PHP:

$exec = json_encode($exec);
        $json = json_decode($exec, TRUE);

        echo $json['hosted_url'];

It just returns { always, in fact even if I put $json['safasfsaf'] it would still return {

What is the issue, the JSON is valid?

You can get hosted_url in this way (ERROR: you missing data $json['data']['hosted_url'])

also you can check your desired output here

<?php

    }
}';

$json = json_decode($a, TRUE);
echo "<pre>";
print_r($json['data']['hosted_url']);

You have error reporting turned off

This error is hidden for you

Warning: Illegal string offset 'hosted_url'

You can turn error reporting on with this code

ini_set('display_errors', 1);
ini_set('display_startup_errors', 1);
error_reporting(E_ALL);

For your code you need to replace $json['hosted_url'] with $json['data']['hosted_url']

$exec = getJson();
$json = json_decode($exec, TRUE);

echo $json['data']['hosted_url'];

Also response is already json so you must not json_encode it

I have noticed that, you are decode json data two time, so you are getting errors.

Hi, i have tried this way.
