Cant Extract data from PHP curl response - php

Question

I learning to use API from: https://rapidapi.com/lambda/api/face-recognition-and-face-detection/endpoints
I want to save or echo albumkey to variable and store in database. I have tried $response->albumkey and didn't work.
here my response below:
{
album: "amanda11",
msg: "Please put this in a safe place and remember it, you'll need it!",
albumkey: "c00bc5d3b1bf64a1ba68f690d4dabee494a2c6fbf48cf8f09c6d41fbece45b7b"
}
And here my code:
$curl = curl_init();
curl_setopt_array($curl, [
CURLOPT_URL => "https://lambda-face-recognition.p.rapidapi.com/album",
CURLOPT_RETURNTRANSFER => true,
CURLOPT_FOLLOWLOCATION => true,
CURLOPT_ENCODING => "",
CURLOPT_MAXREDIRS => 10,
CURLOPT_TIMEOUT => 30,
CURLOPT_HTTP_VERSION => CURL_HTTP_VERSION_1_1,
CURLOPT_CUSTOMREQUEST => "POST",
CURLOPT_POSTFIELDS => "album=amanda11",
CURLOPT_HTTPHEADER => [
"content-type: application/x-www-form-urlencoded",
"x-rapidapi-host: lambda-face-recognition.p.rapidapi.com",
"x-rapidapi-key: 932571abf0msh45cf0f3cef74aacp19e151jsn33e9949a1974"
],
]);
$response = curl_exec($curl);
$err = curl_error($curl);
if ($err) {
echo $err;
} else {
echo $response;
}

Answer 1

You need to parse the JSON before you can access its values. In PHP you do that with json_decode():
$response = curl_exec($curl);
$err = curl_error($curl);
if ($err) {
echo $err;
} else {
$json = json_decode($response);
echo $json->albumkey ;
}
Here's a basic example:
$response = '{
"album": "amanda11",
"msg": "Please put this in a safe place and remember it, you\'ll need it!",
"albumkey": "c00bc5d3b1bf64a1ba68f690d4dabee494a2c6fbf48cf8f09c6d41fbece45b7b"
}';
$json = json_decode($response);
echo $json->albumkey;
