如何从PHP中的构造函数方法返回错误

I am trying to learn PHP web development by doing it the OOP way and have a question about how to return an array of errors from a PHP constructor method. I have a form that a user enters information in, but when I check the data they enter, if they have an error, I want to be able to return that to the page that requested it so that I can display it in a list box above the form. How would I go about doing that? My code is below and is just test code that Im playing with to learn PHP for a website I need to build in the near future.
