Display JSON response using PHP from URL - php

Question

I have a feed from a parcel tracking service that i am trying to integrate into my site. I have a url which allows me to put the tracking number at the end and get a json response. I have multiple objects from this which include some static info such as the senders address and some info which I will need to use a foreach for like the tracking progress.
I believe I have got the string okay however I am not sure how I am meant to display the info.
This is what I have so far:
Example URL:
domain.com/REST_Service/webservice/consignee/SelfshipService.svc/web/Tracking/84941354665
URL Returns:
{

Current PHP:
//set tracking url
$url = "http://www.ocscourier.co.uk/REST_Service/webservice/consignee/SelfshipService.svc/web/Tracking/84941354665";
// create curl resource
$ch = curl_init();
// set url
curl_setopt($ch, CURLOPT_URL, "http://www.ocscourier.co.uk/REST_Service/webservice/consignee/SelfshipService.svc/web/Tracking/84941354665");
//return the transfer as a string
curl_setopt($ch, CURLOPT_RETURNTRANSFER, 1);
curl_setopt($ch, CURLOPT_USERAGENT, 'Mozilla/5.0 (Windows; U; Windows NT 5.1; en-US; rv:1.8.1.13) Gecko/20080311 Firefox/2.0.0.13');
// $output contains the output string
$output = curl_exec($ch);
// close curl resource to free up system resources
curl_close($ch);
//call api
//$json = file_get_contents($url);
$json = json_decode($output);
$Address1 = $json->results[0]->Consignee->Address1;
$Address2 = $json->results[0]->Consignee->Address2;
echo "Address 1: " . $Address1 . ", Address 2: " . $Address2;

Answer 1

Your json string doesn't have any results key (so I'm not sure why you trying to access results[0].
You can just use
$Address1 = $json->Consignee->Address1;
$Address2 = $json->Consignee->Address2;
Check this code:
$s = <<< END
{
"Agent": null,
"Consignee": {
"Address1": "25 HEATHFIELD ROAD",
"Address2": "SHOLING",
"Address3": "",
"Code": null,
"Company": "ERIK HANSON",
"Country": "GREAT BRITAIN",
"Dept": "",
"Email": "ERIK.HANSON66#GOOGLEMAIL.COM",
"Name": "",
"Phone": "07770320490",
"Postcode": "SO19 1DL",
"State": "HANTS",
"Town": "SOUTHAMPTON"
},
"CrossIdx": "",
"Error": null,
"NonDel": null,
"POD": {
"Date": "13 Jul 2016",
"Status": "Harnett",
"Time": "09:17"
},
"Pieces": 1,
"PosErr": 0,
"Tracks": [
{
"Date": "13 Jul 2016",
"Status": "Out for delivery",
"Time": "07:10"
},
{
"Date": "13 Jul 2016",
"Status": "At Delivery location Portsmouth",
"Time": "02:24"
},
{
"Date": "13 Jul 2016",
"Status": "At Delivery location Portsmouth",
"Time": "02:22"
},
{
"Date": "12 Jul 2016",
"Status": "Arrived At Ryton",
"Time": "22:12"
},
{
"Date": "12 Jul 2016",
"Status": "Preparing for despatch",
"Time": "14:00"
},
{
"Date": "12 Jul 2016",
"Status": "Scanned into OCS HEATHROW LONDON",
"Time": "13:59"
},
{

},
{

},
{

"Status": "Collected from Customer",
"Time": "09:32"
}
],
"Weight": 7
}
END;
$json = json_decode($s);
$Address1 = $json->Consignee->Address1;
$Address2 = $json->Consignee->Address2;
echo "Address 1: " . $Address1 . ", Address 2: " . $Address2;
Here is the output:
Address 1: 25 HEATHFIELD ROAD, Address 2: SHOLING

Answer 2

Below is json string in $json variable and access with RecursiveIteratorIterator
Example
$json='{
"Agent": null,
"Consignee": {
"Address1": "25 HEATHFIELD ROAD",
"Address2": "SHOLING",
"Address3": "",
"Code": null,
"Company": "ERIK HANSON",
"Country": "GREAT BRITAIN",
"Dept": "",
"Email": "ERIK.HANSON66#GOOGLEMAIL.COM",
"Name": "",
"Phone": "07770320490",
"Postcode": "SO19 1DL",
"State": "HANTS",
"Town": "SOUTHAMPTON"
},
"CrossIdx": "",
"Error": null,
"NonDel": null,
"POD": {
"Date": "13 Jul 2016",
"Status": "Harnett",
"Time": "09:17"
},
"Pieces": 1,
"PosErr": 0,
"Tracks": [
{
"Date": "13 Jul 2016",
"Status": "Out for delivery",
"Time": "07:10"
},
{
"Date": "13 Jul 2016",
"Status": "At Delivery location Portsmouth",
"Time": "02:24"
},
{
"Date": "13 Jul 2016",
"Status": "At Delivery location Portsmouth",
"Time": "02:22"
},
{
"Date": "12 Jul 2016",
"Status": "Arrived At Ryton",
"Time": "22:12"
},
{
"Date": "12 Jul 2016",
"Status": "Preparing for despatch",
"Time": "14:00"
},
{
"Date": "12 Jul 2016",

},
{
"Date": "14 Jun 2016",
"Status": "Shipment prepared by customer",

},
{
"Date": "02 Jan 2003",
"Status": "Collected from Customer",

}
],

}';
$jsonIterator = new RecursiveIteratorIterator(
new RecursiveArrayIterator(json_decode($json, TRUE)),
RecursiveIteratorIterator::SELF_FIRST);
foreach ($jsonIterator as $key => $val) {
if(is_array($val)) {
echo "$key:\n</br>";
} else {
echo "$key => $val\n";
}
}
