How can PHP developers efficiently extract and manipulate data from complex JSON structures?

To efficiently extract and manipulate data from complex JSON structures in PHP, developers can use the built-in json_decode function to convert JSON data into a PHP array or object. Once the JSON data is converted, developers can then easily access and manipulate the data using array or object notation. 

$jsonData = '{
    "name": "John Doe",
    "age": 30,
    "address": {
        "street": "123 Main St",
        "city": "New York",
        "zipcode": "10001"
    },
    "hobbies": ["reading", "coding", "gaming"]
}';

$data = json_decode($jsonData);

// Accessing data from the JSON structure
echo $data->name; // Output: John Doe
echo $data->address->city; // Output: New York

// Manipulating data in the JSON structure
$data->age = 31;
$data->hobbies[] = "hiking";

$newJsonData = json_encode($data);
echo $newJsonData;
