PHP Get Returned Value From Constructor

问题:

I am confused, I have a PHP class with a constructor:

class Test {
   public function __construct() {
      return "some text";
   }
}

Then I instanciate an object:

$t = new Test();

I would expect the contents of $t to be "some text":

print_r($t);

But it is:

Test Object
(
)

How do I get the returned value "some text" from the constructor?

回答1:

You cannot return anything from a constructor. The new keyword will always result in a new object, it does not matter what you return from the constructor.
