Hello everyone, This is my array and I want to echo value of only "id" i.e. I want to get value as '115' of key- "id". Please guide me how to make a foreach for this one? I have tried lots of variations but none worked :(

TIA :)

UPDATE- I have tried this but did not get any result:

foreach($res as $k=>$t)
{
  echo $t["product_details"]["id"]; 
}

Why don't you put the code in of what you think your best variation is and then we'll help you out. — Difster, Jul 22 '17 at 23:41
You say `foreach`, but the code you post is a JSON for 1 object. — Accountant م, Jul 22 '17 at 23:43
Hello, I tried json_decode n this but its still not working. Can anyone please give me a working code? Its really urgent — user2452, Jul 22 '17 at 23:46
@user2452 `json_decode` [worked with me](https://eval.in/836362) . The string you posted is a valid JSON. — Accountant م, Jul 22 '17 at 23:49
@Accountantم Can you please provide me with the working code sir? — user2452, Jul 22 '17 at 23:51

The code you posted seems to be trying to get the ID of productdetails which is nowhere in the data you showed us. — takendarkk, Jul 23 '17 at 00:10
@user2452 You have to put a reliable example of your array. You put here an object , and I'm sure you have an array , so every answer you are going to get will work on that format of the object in the question but none of them will work with your real array you have. — Accountant م, Jul 23 '17 at 00:14

Before you can use the JSON as an array you need to convert it first. use json_decode() for that.

<?php 
$json='{"2b44928ae11fb9384c4cf38708677c48":{"id":"115","qty":3,"option":"{\"color\":{\"title\":\"Color\",\"value\":\"\"}}","price":150,"name":"Nightwear","shipping":"5","tax":3,"image":"http:\/\/localhost\/plus\/uploads\/product_image\/product_115_1_thumb.jpg","coupon":"","rowid":"2b44928ae11fb9384c4cf38708677c48","subtotal":450}}';

$array = json_decode($json, true);

foreach($array as $key=>$value){
    echo $value['id'];
}
?>

Thank you so much :) Highly appreciated. – user2452 Jul 22 '17 at 23:58
The problem with this code is it's is looping in the outer object **properties**. And lucky you are the outer object has only 1 property, that is `2b44928ae11fb9384c4cf38708677c48`and this property is an object too that has the rest of the other data. Your code will not work if this object is an element in an array. – Accountant م Jul 23 '17 at 00:33
BTW, this is not your fault, this is the OP fault because he didn't provide a reliable example of the array, your code answers the question 100% – Accountant م Jul 23 '17 at 00:36

Assuming you have an array of objects like you provided in your post, I have put your object in an array for testing

<?php
$json = '[{"2b44928ae11fb9384c4cf38708677c48":{"id":"115","qty":3,"option":"{\"color\":{\"title\":\"Color\",\"value\":\"\"}}","price":150,"name":"Nightwear","shipping":"5","tax":3,"image":"http:\/\/localhost\/plus\/uploads\/product_image\/product_115_1_thumb.jpg","coupon":"","rowid":"2b44928ae11fb9384c4cf38708677c48","subtotal":450}},'.
         '{"2b44928ae11fb9384c4cf38708677c48":{"id":"116","qty":3,"option":"{\"color\":{\"title\":\"Color\",\"value\":\"\"}}","price":150,"name":"Nightwear","shipping":"5","tax":3,"image":"http:\/\/localhost\/plus\/uploads\/product_image\/product_115_1_thumb.jpg","coupon":"","rowid":"2b44928ae11fb9384c4cf38708677c48","subtotal":450}}]';
$json = json_decode($json);
foreach ($json as $object){
    $propsArray = get_object_vars($object);
    reset($propsArray);
    echo $object->{key($propsArray)}->id . "<br>\n";
}
exit;

this outputs

115
116

$json='{"2b44928ae11fb9384c4cf38708677c48":{"id":"115","qty":3,"option":"{\"color\":{\"title\":\"Color\",\"value\":\"\"}}","price":150,"name":"Nightwear","shipping":"5","tax":3,"image":"http:\/\/localhost\/plus\/uploads\/product_image\/product_115_1_thumb.jpg","coupon":"","rowid":"2b44928ae11fb9384c4cf38708677c48","subtotal":450}}';

$array = json_decode($json, true); // convert json string to array

$result = array_column($array, 'id'); // find matching array key and return values in array

foreach ($result as $value) { // echo each value with foreach loop
    echo $id . '<br>';
}
