我很困惑,我有一个带有构造函数的 PHP 类:
I am confused, I have a PHP class with a constructor:
class Test {
public function __construct() {
return "some text";
}
}
然后我实例化一个对象:
Then I instanciate an object:
$t = new Test();
我希望 $t 的内容是一些文本":
I would expect the contents of $t to be "some text":
print_r($t);
但它是:
Test Object
(
)
如何从构造函数中获取返回值"some text"
?
How do I get the returned value "some text"
from the constructor?
你不能从构造函数return
任何东西.new
关键字总是会产生一个新的对象,不管你从构造函数中return
什么.
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.
