Display JSON Response specific keys/values using PHP - php

Question

I want to display specific keys and values from the following JSON Response I am using API to fetch the JSON values:
[
{
"tracking_data": {
"track_status": 1,
"shipment_status": 7,
"shipment_track": [
{
"id": 42719783,
"pickup_date": "2020-07-20 19:07:00",
"delivered_date": "2020-07-22 11:36:00",
"weight": "0.15",
"packages": 1,
}
],
"shipment_track_activities": [
{
"date": "2020-07-22 11:36:00",
"status": "DLVD",
"activity": "Delivered Shipment Delivered by SR: VasudevDengi, MobileNo: 7999869145, DeliveryDate: 2020-07-22 11:36:30, Receiver Name: Suman Rajnod ",
"location": "IDR/RJN, Indore, MADHYA PRADESH"
},
{
"date": "2020-07-22 10:21:00",
"status": "OFD",
"activity": "Out for Delivery Out for delivery: 104688-VasudevDengi-PDS20204102119104688-FromMob",
"location": "IDR/RJN, Indore, MADHYA PRADESH"
},
{
"date": "2020-07-22 08:09:00",
"status": "RAD",
"activity": "Reached at Destination InScan ( Shipment Auto Bagout )",
"location": "IDR/RJN, Indore, MADHYA PRADESH"
},
{
"date": "2020-07-21 07:07:00",
"status": "IT",
"activity": "InTransit Shipment added in ParentBagNo: NXBB024886",
"location": "IDR/IDR, Indore, MADHYA PRADESH"
}
]
I am trying to display with this php code but it's giving blank screen, also the JSON values (I mentioned above) are assigned to $response variable.
$js = json_decode($response, true);
foreach($js as $return){
echo $return['tracking_data']['track_status'];
} ?>
Addition - I can display track_status value following solution provided #Aashishgaba thanks,
Can you also guide me to display data like "pickup_date" and "shipment_track_activities" as you can see there is multiple data based on dates.

Answer 1

$js = json_decode($response, true);
foreach($js as $return){
echo $return['tracking_data']['track_status'];
foreach($return['tracking_data']['shipment_track'] as $st){
echo $st['pickup_date'];
}
foreach($return['tracking_data']['shipment_track_activities'] as
$sta){
echo $sta['date'];
echo $sta['status'];
}
} ?>
