Are there existing libraries or tools that can simplify the process of parsing and extracting data from JSON responses in PHP?

Parsing and extracting data from JSON responses in PHP can be simplified by using libraries such as `json_decode()` and tools like `Guzzle`, which can handle HTTP requests and JSON responses efficiently. These tools can help parse the JSON data into PHP arrays or objects, making it easier to extract the desired information.

// Example code using Guzzle to make an HTTP request and parse JSON response
require 'vendor/autoload.php'; // Include Guzzle library

$client = new GuzzleHttp\Client();
$response = $client->request('GET', 'https://api.example.com/data');
$data = json_decode($response->getBody(), true);

// Extracting data from JSON response
if(isset($data['key'])) {
    $value = $data['key'];
    echo $value;
} else {
    echo 'Key not found in JSON response';
}
