php动态类建设 [英] Php dynamic class construction

问题描述

我正试图避免使用eval.我可以像这样动态地实例化一个类:

I'm trying to avoid the use of eval. I can dynamically instantiate a class like this:

class myclass {}

$my_class_name = 'myclass';
$obj = new $myclass();

如果构造函数如下:

class myclass {
    public function __construct( $argument1, $argument2 ) {}
}

并且我在数组中具有参数的值，如何动态实例化类并将其传递给动态参数?请注意，我无法修改该类，因此我必须努力使用它.

and i have the values of the arguments in an array, how can i dynamically instantiate the class and pass it dynamic arguments? Mind that I have no way to modify the class, so I have to work on the way of using it.

谢谢

推荐答案

ReflectionClass::newInstanceArgs seems to be just the thing you're looking for.
