Question

The response is received in JSON, $requestBody holds the json response. The type of that class is stdclass.

Now, if I access it using

   $myCar=$requestBody->Car;

The value in $myCar is “Alpha”. So, far so good.

I have defined a constants like, defined in “MyConstants.php”

   define("ITEM1","Car");

So, I am trying to access values from $requestBody using Constant. But I get nil. the code is listed below in “index.php”

<?php 

include 'MyConstants.php';

//Works 
$key=constant("ITEM1");
$carStr=$requestBody->key;

//Does not work 
$carStr2=$requestBody->constant("ITEM1");
?>

Answer 1

Try the following:

$requestBody->{ITEM1}

You might also consider to decode the json to an array:

$requestBody = json_decode($json, true);
$requestBody[ITEM1];
