newInstance();
newInstanceArgs($args);In this example, we define a MyClass class with a constructor that takes two arguments. We then use the ReflectionClass __construct method to create a new instance of the ReflectionClass class, and then use the newInstanceArgs method to create a new instance of the MyClass class, passing in an array of arguments. Based on the code examples and syntax, the package library for these methods is likely the built-in PHP ReflectionClass library. This package provides classes and methods for introspecting PHP classes, interfaces, functions, methods and extensions.
