Get the value from Rest post API - php

Question

Output when success
string(66)
"{"status":true,"message":"success","data":{"amountDue":"-504.20"}}"
Output when error
string(119) "{"status":false,"message":"An error occured while getting
full subscriber profile: Subscription not found MPP servers"}"
How should I write in php to get the amount due from the output? I am new to REST api. Can someone show me ? Thank you

Answer 1

That is a JSON-encoded response. Use json_decode() to convert the string back into an array, and then access the array element:
$output = '{"status":true,"message":"success","data":{"amountDue":"-504.20"}}';
$results = json_decode($output,true);
if($results["status"])
{
echo "Success! Data: " . print_r($results,true);
}

I assume that you can at least send proper request to the endpoint and you are able to capture the response.
You receive a json string which must be parses so if:
$response = '{"status":true,"message":"success","data":{"amountDue":"-504.20"}}';
$responseArray = json_decode($response, true);
Then you will get a responseArray as associated array (the second parameter) so you can get amount due like that
$amountDue = $responseArray['data']['amountDue'];
You could also parse json data into an StdClass which turn all fields in json into an object's property. To do that abandon the second parameter in json_decode function
$resultObj = json_decode($response);
$amountDue = $resultObj->data['amountDue'];
All depends on your requests.
