How can JSON data be efficiently processed and filtered in PHP, and what are the advantages of using JSON over HTML for data retrieval and manipulation?

To efficiently process and filter JSON data in PHP, you can use the json_decode function to convert JSON data into a PHP array or object. Once converted, you can easily manipulate and filter the data using PHP array functions or loops. JSON is advantageous over HTML for data retrieval and manipulation because it is a lightweight data-interchange format that is easier to parse and work with programmatically. 

// Sample JSON data
$jsonData = '{"users": [{"name": "Alice", "age": 30}, {"name": "Bob", "age": 25}, {"name": "Charlie", "age": 35}]}';

// Decode JSON data into PHP array
$data = json_decode($jsonData, true);

// Filter users older than 30
$filteredUsers = array_filter($data['users'], function($user) {
    return $user['age'] > 30;
});

// Output filtered users
print_r($filteredUsers);
