What is the process for querying JSON child items in PHP?

When querying JSON child items in PHP, you can use the json_decode function to convert the JSON data into an associative array. You can then access the child items by specifying their keys in the array. 

// JSON data
$jsonData = '{
    "parent": {
        "child1": "value1",
        "child2": "value2"
    }
}';

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

// Access child items
$child1Value = $data['parent']['child1'];
$child2Value = $data['parent']['child2'];

echo $child1Value; // Output: value1
echo $child2Value; // Output: value2
