How can one access a variable or array in a class with a runtime-defined class name in PHP?

When trying to access a variable or array in a class with a runtime-defined class name in PHP, you can use variable variables to achieve this. By using the double dollar sign ($$) followed by the runtime-defined class name, you can dynamically access the variable or array within that class. 

class MyClass {
    public $data = ['value1', 'value2', 'value3'];
}

$className = 'MyClass';
$instance = new $className();

// Accessing the array in the class with a runtime-defined class name
$dynamicArray = $instance->data;

print_r($dynamicArray);
