php - 我们怎么称呼这个？

Question

我想知道我们如何称呼这种作业。

<?php
class SimpleClass
{
    public $var1;
    public $var2;
    public $var3;

    public function SimpleClass()
    {
        $this->var1 = 'one';
        $this->var2 = 'two';
        $this->var3 = 'three';
    }
}

function test()
{
    $objSc = new SimpleClass();
    $objSc->var4 = 'WTF?!'; # <-- what do we call this?
    var_dump($objSc);
}

test();
?>

更好的引用或链接。提前致谢!

编辑:我正在为它寻找一个技术术语......好吧，如果我们有的话。

我认为这是重载。

Overloading in PHP provides means to dynamically "create" properties and methods. These dynamic entities are processed via magic methods one can establish in a class for various action types.

The overloading methods are invoked when interacting with properties or methods that have not been declared or are not visible in the current scope.
