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: 

{ "Agent": null, "Consignee": { "Address1": "25 HEATHFIELD ROAD", "Address2": "SHOLING", "Address3": "", "Code": null, "Company": "ERIK HANSON", "Country": "GREAT BRITAIN", "Dept": "", "Email": "[email protected]", "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" }, { "Date": "12 Jul 2016", "Status": "Consignment details verified", "Time": "13:59" }, { "Date": "14 Jun 2016", "Status": "Shipment prepared by customer", "Time": "11:20" }, { "Date": "02 Jan 2003", "Status": "Collected from Customer", "Time": "09:32" } ], "Weight": 7 }

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;

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": "[email protected]", "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" }, { "Date": "12 Jul 2016", "Status": "Consignment details verified", "Time": "13:59" }, { "Date": "14 Jun 2016", "Status": "Shipment prepared by customer", "Time": "11:20" }, { "Date": "02 Jan 2003", "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

When accessing it as per your example I am still getting an error. Notice: Trying to get property of non-object in parcel-tracking.php on line 29
Maybe your string is not what you added in the example? If you run the exact code in my answer it works (check here: sandbox.onlinephpfunctions.com/code/…)
This is my full code: sandbox.onlinephpfunctions.com/code/… If you go to the URL you will see the output
The problem is with the URL. Did you check it (in your browser)? :)
Please double check. Copy & Paste the exact URL from the code you posted :)

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": "[email protected]", "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" }, { "Date": "12 Jul 2016", "Status": "Consignment details verified", "Time": "13:59" }, { "Date": "14 Jun 2016", "Status": "Shipment prepared by customer", "Time": "11:20" }, { "Date": "02 Jan 2003", "Status": "Collected from Customer", "Time": "09:32" } ], "Weight": 7 }'; $jsonIterator = new RecursiveIteratorIterator( new RecursiveArrayIterator(json_decode($json, TRUE)), RecursiveIteratorIterator::SELF_FIRST); foreach ($jsonIterator as $key => $val) { if(is_array($val)) { echo "$key:\n</br>"; } else { echo "$key => $val\n"; } }

OUTPUT:

 Agent => Consignee: Address1 => 25 HEATHFIELD ROAD Address2 => SHOLING Address3 => Code => Company => ERIK HANSON Country => GREAT BRITAIN Dept => Email => [email protected] Name => Phone => 07770320490 Postcode => SO19 1DL State => HANTS Town => SOUTHAMPTON CrossIdx => Error => NonDel => POD: Date => 13 Jul 2016 Status => Harnett Time => 09:17 Pieces => 1 PosErr => 0 Tracks: 0: Date => 13 Jul 2016 Status => Out for delivery Time => 07:10 1: Date => 13 Jul 2016 Status => At Delivery location Portsmouth Time => 02:24 2: Date => 13 Jul 2016 Status => At Delivery location Portsmouth Time => 02:22 3: Date => 12 Jul 2016 Status => Arrived At Ryton Time => 22:12 4: Date => 12 Jul 2016 Status => Preparing for despatch Time => 14:00 5: Date => 12 Jul 2016 Status => Scanned into OCS HEATHROW LONDON Time => 13:59 6: Date => 12 Jul 2016 Status => Consignment details verified Time => 13:59 7: Date => 14 Jun 2016 Status => Shipment prepared by customer Time => 11:20 8: Date => 02 Jan 2003 Status => Collected from Customer Time => 09:32 Weight => 7
