                    }
        }
    "2":
        {
            value0":
                    {
                        "id":0,
                        "status":0,
                        "quantity":"132"
                    },
            "value1":
                    {
                        "id":1,
                        "status":1,
                        "quantity":"123"
                    },
        }
}

I want to change the status of value0 from key 1, to 1. How can I acheive this?

Convert JSON to array by using json_decode. Make the update in the array. Then convert the array into JSON by using json_encode. — manian

$new_data = json_decode($data,true); $new_data[1]["value0"]["status"]=1; $data = json_encode($new_data); echo $data; — JYoThI

Oh thank you @manian, but when I tried json_endcode, my json changed to {"1":{"value0":{"status":1}}}. — MF. Hujaeri

use json_decode() and json_enocde()

$data = json_decode($data,true);  
$data["1"]["value0"]["status"]=1;   
$data = json_encode($data);
echo $data;

shouldn't it be ["1"] instead of [1] since its an assoc array and [1] would trigger second array element, which is key "2"?
