Turning a string into an associative array in PHP - php

Question

I am using PHP with cURL to make requests to an API.
The API responds with an encrypted string which I then have to use json_decode on and run it through a pre-defined decrypt method that returns a string.
So I have something like this:
echo $response;
$decodedResponse = json_decode($response, true);
// New instance of Decrypt
$decrypt = new Decrypt();
$decryptedResponse = $decrypt->decrypt($decodedResponse);
echo $decryptedResponse;
Using var_dump($decryptedResponse) yields string(960) but the string looks like a JSON array.
{"Title":"Mr","Forenames":"Steve"}
So what is the best way to rip apart this string so that I can use the variables through an associative array?
I had already tried:
foreach(decryptedResponse as $data)
{
echo $data['Title'];
}
But this outputted nothing on the screen.
Am I misinterpreting the use of json_decode?
As many have stated it seems you have to decode twice, I'll look into this and share my findings.

Answer 1

You need to json_decode again on the decrypt result
$decodedResponse = json_decode($response, true);
// New instance of Decrypt
$decrypt = new Decrypt();
$decryptedResponse = $decrypt->decrypt($decodedResponse);
$decryptedArry = json_decode($decryptedResponse, true);
var_dump($decryptedArry);
echo $decryptedArry['Title'];

Answer 2

As you told Using `var_dump($decryptedResponse)` yields string(960) but the string looks like a JSON means your decrypt duration convert it again json. You can try bellow code it may resolve your issue
$decodedResponse = json_decode($response, true);
// New instance of Decrypt
$decrypt = new Decrypt();
$decryptedResponse = $decrypt->decrypt($decodedResponse);
$decryptedResponse = json_decode($response, true);
foreach(decryptedResponse as $data)
{
echo $data['Title'];
}

Answer 3

The code below shows that the json_decode works like you want it to but it seems like your Decryption class does something weird.
$response = '{"Title":"Mr","Forenames":"Steve"}';
$decodedResponse = json_decode($response, true);
var_dump($decodedResponse);
echo $decodedResponse["Title"];
