Get data from json array - Undefined index error - php

Question

Below is json response and I have problems getting shipping_address data.
{
"orders": [{
"created_at": "2015-01-04T02:20:03+01:00",
"financial_status": "paid",
"id": 384536708,
"total_price": "45.00",
"line_items": [{
"fulfillment_service": "manual",
"fulfillment_status": null,
"gift_card": false,
"grams": 0,
"price": "45.00",
"quantity": 1,
"requires_shipping": true,
"taxable": true,
"title": "test",
"vendor": "test",
"name": "test",
"properties": [],
"product_exists": true,
"fulfillable_quantity": 1,
"tax_lines": []
}],
"shipping_address": {
"address1": "Street 20",
"address2": "",
"city": "City",
"company": "",
"country": "USA",
"first_name": "Name",
"last_name": "Surname",
"latitude": 45.000000,
"longitude": 10.000000,
"phone": "",
"province": "",
"zip": "12345",
"name": "Name Surname",
"country_code": "US",
"province_code": null
}
}, [...]
I can get orders with this code:
$content = file_get_contents($url);
$json = json_decode($content, true);
foreach($json['orders'] as $order){
echo "<td>".$order['id']."</td>";
}
But when I try to get shipping_address data like this:
foreach ($json['shipping_address'] as $sa) {
echo "<td>".$sa['name']."</td>";
}
Then i get: Notice: Undefined index: shipping_address and Warning: Invalid argument supplied for foreach()
Am I targeting array wrong?

Answer 1

It should be -
foreach ($json['orders']['shipping_address'] as $sa) {
Try this -
foreach($json['orders'] as $order){
echo "<td>".$order['id']."</td>";
echo "<td>".$order['shipping_address']['name']."</td>";
}

Answer 2

foreach ($json['orders']['shipping_address'] as $sa) {
echo "<td>".$sa['name']."</td>";
}

Answer 3

Try this :
$content = file_get_contents($url);
$json = json_decode($content, true);
foreach($json as $orders){
foreach($orders as $odarr){
foreach($odarr['shipping_address'] as $shipadd){
echo $shipadd['address1'];
}
}
}
