How can PHP developers effectively handle and parse JSON responses from API requests, like the one from the Twitch API, to extract relevant data?

To effectively handle and parse JSON responses from API requests in PHP, developers can use the built-in `json_decode()` function to convert the JSON data into an associative array or object. This allows easy access to the relevant data within the response for further processing or display. 

// Make an API request and get the JSON response
$response = file_get_contents('https://api.twitch.tv/helix/streams?user_login=ninja');

// Decode the JSON response into an associative array
$data = json_decode($response, true);

// Access and extract relevant data from the response
if(isset($data['data'][0]['viewer_count'])) {
    $viewerCount = $data['data'][0]['viewer_count'];
    echo "Ninja currently has $viewerCount viewers on Twitch.";
}
