How can PHP developers efficiently parse and extract specific data, such as locality, from the response returned by the Google API when querying postal codes?

To efficiently parse and extract specific data like locality from the Google API response when querying postal codes, PHP developers can use the json_decode function to convert the API response into an associative array. Then, they can navigate through the array to extract the desired data, such as locality, using the appropriate keys. 

// Make a request to the Google API and get the response
$response = file_get_contents('https://maps.googleapis.com/maps/api/geocode/json?address=90210');

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

// Extract the locality from the response
$locality = $data['results'][0]['address_components'][1]['long_name'];

// Output the locality
echo $locality;
