有没有办法在没有构造函数的情况下将成员变量分配给类的对象？

Question

I want to do something like the following:

class SomeOtherClass {}

class Test
 {
        public $member = new SomeOtherClass();
 }

The only problem is that I do not want to use a constructor, because the 'Test' class should extend another class and should not override the constructor. Is this actually possible in PHP?

Answer 1

You can extend parent constructor in Test like this:

class Test extends SomeClass
{
    public $member;

    function __construct() {
        $this->member = new SomeOtherClass();
        parent::__construct();
    }
}
