PHP 中的 SplObjectStorage 和糖语法

发布于 2024-12-19 01:22:45 字数 533 浏览 3 评论 0原文

快一个；我怀疑这是可能的，但是有什么方法可以利用 PHP 的 array($key => $value); 语法来处理 SplObjectStorage 对象吗？

我的意思是，有没有这样的方法来实现：

$store = // ?
    new KeyObject() => new ValueObject(),
    new KeyObject() => new ValueObject(),
    // ...

在上下文中初始化对象存储？目前我只是使用：（并且可能会继续，考虑到这种可能性完全不可能）

$store = new SplObjectStorage();
$store[new KeyObject()] = new ValueObject();
$store[new KeyObject()] = new ValueObject();
// ...

会很好，高度怀疑它，但也许有人知道得更好。

Quick one; I doubt it's possible, but is there any way to take advantage of the array($key => $value); syntax of PHP with regard to SplObjectStorage objects?

What I mean is, is there any such way to achieve:

$store = // ?
    new KeyObject() => new ValueObject(),
    new KeyObject() => new ValueObject(),
    // ...

In the context initializing an object store? As of the moment I'm simply using: (and will probably continue, considering the sheer unlikeliness of this being a possibility)

$store = new SplObjectStorage();
$store[new KeyObject()] = new ValueObject();
$store[new KeyObject()] = new ValueObject();
// ...

Would be nice, highly doubting it, but maybe someone knows better.

虽然这将是一种更简洁的语法，但不幸的是这是不可能的。您可以做的最好的事情是：

$store[new KeyObject()] = new ValueObject();

或者

$store->append( new KeyObject(), new ValueObject());

将对象添加到 SplObjectStorage 时。

While it would be a more concise syntax, unfortunately it's not possible. The best you can do is either:

$store[new KeyObject()] = new ValueObject();

$store->append( new KeyObject(), new ValueObject());

When adding object to an SplObjectStorage.

为什么不做这样的事情：

$store = new SplObjectStorage();

$data = array(
    array(new KeyObject, new ValueObject),
    array(new KeyObject, new ValueObject),
    array(new KeyObject, new ValueObject),
);

foreach($data as $item) {
    list($key, $value) = $item;
    $store->attach($key, $value);
}

它不漂亮，但至少简洁。

Why not do something like that:

$store = new SplObjectStorage();

$data = array(
    array(new KeyObject, new ValueObject),
    array(new KeyObject, new ValueObject),
    array(new KeyObject, new ValueObject),
);

foreach($data as $item) {
    list($key, $value) = $item;
    $store->attach($key, $value);
}

It's not beautiful but it's at least concise.
