在 PHP 中，你可以在同一行实例化一个对象并调用一个方法吗?

问题描述：

我想做的是这样的:

$method_result = new Obj()->method();

而不必这样做:

$obj = new Obj();
$method_result = $obj->method();

在我的具体情况下，结果对我来说实际上并不重要.但是，有没有办法做到这一点?

The result doesn't actually matter to me in my specific case. But, is there a way to do this?

您要求的功能可从 PHP 5.4 获得.以下是 PHP 5.4 中的新功能列表:

The feature you have asked for is available from PHP 5.4. Here is the list of new features in PHP 5.4:

以及新功能列表中的相关部分:

And the relevant part from the new features list:

添加了实例化时的类成员访问权限，例如(new Foo)->bar().

Class member access on instantiation has been added, e.g. (new Foo)->bar().
