Decoding the JSON in PHP

Question

I need help decoding the JSON below in PHP. I am facing a challenge doing that so I need assistance. Below is my JSON and I need the values of the attributes in the return parameter as well as the RESULT array.

{"return":"{"MESSAGE":"INVOICE IS ACCEPPTED - ECHO THE PAYMENT URL","CODE":"0","SUCCESS":true,"RESULT":[{"DESCRIPTION":"Payment for business registration","PAYMENTTOKEN":"6354c166-cdb1-459a-8a7c-e23f9d3a0dd6","APIPAYREDIRECTURL":"https://testcalpay.caleservice.net/pay/secure/index.php?paytoken=6354c166-cdb1-459a-8a7c-e23f9d3a0dd6","QRLCODEURL":"https://testcalpay.caleservice.net/paymentqrs/BK3NUFI936.png","PAYMENTCODE":"BK3NUFI936","MOMOSTATUS":"1","ORDERCODE":"INV2022003","MOMOPAYMENT":"FAILED","SHORTPAYCODE":"10000645"}]}"}

And this is my code:

$msg = $obj['return']->MESSAGE; var_dump($msg);

I get the error:
Attempt to read property "MESSAGE" on string in

Answer 1

The json you posted is invalid. Check out the screenshot below. The object seems to be enclosed by double quotations. I guess it is supposed to be a regular object so don't enclose it by double quotations unless you want it as a string data.

And below is the json in which double quotations are removed from the object.

{
    "return": {
        "MESSAGE": "INVOICE IS ACCEPPTED - ECHO THE PAYMENT URL",
        "CODE": "0",
        "SUCCESS": true,
        "RESULT": [
            {
                "DESCRIPTION": "Payment for business registration",
                "PAYMENTTOKEN": "6354c166-cdb1-459a-8a7c-e23f9d3a0dd6",
                "APIPAYREDIRECTURL": "https://testcalpay.caleservice.net/pay/secure/index.php?paytoken=6354c166-cdb1-459a-8a7c-e23f9d3a0dd6",
                "QRLCODEURL": "https://testcalpay.caleservice.net/paymentqrs/BK3NUFI936.png",
                "PAYMENTCODE": "BK3NUFI936",
                "MOMOSTATUS": "1",
                "ORDERCODE": "INV2022003",
                "MOMOPAYMENT": "FAILED",
                "SHORTPAYCODE": "10000645"
            }
        ]
    }
}

Answer to your question, you could decode json like above using json_decode() . See example below.

Working example

<?php
// Enter your code here, enjoy!
$obj = '{"return":{"MESSAGE":"INVOICE IS ACCEPPTED - ECHO THE PAYMENT URL","CODE":"0","SUCCESS":true,"RESULT":[{"DESCRIPTION":"Payment for business registration","PAYMENTTOKEN":"6354c166-cdb1-459a-8a7c-e23f9d3a0dd6","APIPAYREDIRECTURL":"https://testcalpay.caleservice.net/pay/secure/index.php?paytoken=6354c166-cdb1-459a-8a7c-e23f9d3a0dd6","QRLCODEURL":"https://testcalpay.caleservice.net/paymentqrs/BK3NUFI936.png","PAYMENTCODE":"BK3NUFI936","MOMOSTATUS":"1","ORDERCODE":"INV2022003","MOMOPAYMENT":"FAILED","SHORTPAYCODE":"10000645"}]}}';

$parsed_json = json_decode($obj);
var_dump($parsed_json->return);
var_dump($parsed_json->return->RESULT);
