PHP inheritance issue

Question

I googled for this for quite awhile. I think I am missing some big concept, but I can't figure out why this won't work

//SomeClass.php

class SomeClass 
{
    protected $something;
    public function __construct() {
        $this->something = 'password';
    }
    public function test() {
        return ($this->something);
    }
}

//OtherClass.php

require_once('SomeClass.php');
class OtherClass extends SomeClass
{   
    public function __construct() {
        echo parent::test();
    }
}

What is the deal here?

Answer 1

您应该在调用parent :: test（）之前先调用parent :: __ construct（）。

Answer 2

构造函数不得返回任何值。
