How can JSON decoding impact the instantiation of objects in PHP?

When decoding JSON data in PHP, the decoded objects are typically created as stdClass objects instead of instances of custom classes. To instantiate objects of custom classes while decoding JSON, you can use the json_decode() function with the second parameter set to true to return associative arrays. Then, you can iterate over the decoded data and create instances of your custom classes using the array data. 

$jsonData = '{"name": "John Doe", "age": 30}';
$decodedData = json_decode($jsonData, true);

class Person {
    public $name;
    public $age;

    public function __construct($name, $age) {
        $this->name = $name;
        $this->age = $age;
    }
}

$person = new Person($decodedData['name'], $decodedData['age']);
