Answer 1

your code is completely current! and it works like charm!
but you made a very ambiguous mistake in your JSON code
you're using this ” instead of " (double quotes) there "david” <----
they exactly look the same!
and also you missed {} in the beginning and end of your JSON code
checkout your json code here it's the best tool for this
<?php
$code = '{
"top_ownerships": [{
"owner": {
"user": {
"username": "david"
},
"profile_img_url": "",
"address": "",
"config": ""
},
"quantity": "1"
}]
}';
$decodedData = json_decode($code, true);
$owner = $decodedData['top_ownerships'][0]['owner'];
$username = $owner['user']['username'];
echo $username;
?>

Answer 2

To start with, it's important you understand how to access json fields and key php;
Assuming the above values are stored in a file known as data.json, we can extract the values like this:
$data = file_get_contents('data.json');
//the second parameter turns the objects into an array
$decodedData = json_decode($data, true);
$owner = $decodedData['top_ownerships'][0]['owner'];
$username = $owner['user']['username'];
//echo $username
The above would work if your json file or data is properly encoded.

Answer 3

first you have to store your JSON into a variable, lets call it $json.
$jsonArray = json_decode($json,true);
And set your key name, the key you want from your JSON.
$key = "owner";
$owner= $jsonArray[$key];
You also can read like an object:
$owner= $jsonObj->$key;

Answer 4

Try
$object = json_decode('{"owner": {"user": {"username": "david”},"profile_img_url": "","address": "","config": ""},"quantity": "1"}')
echo $object->owner->user->username
This will make the JSON an object that you can access by using the -> accessor
