PHP - 是在foreach循环本地的foreach循环中定义的变量吗?

已采纳

Let's say I have this foreach:

foreach ($items as $item) {
    $name = $item->name;
    $number = $item->number;
}

and I want to use them else where on the same page - say below the containing div like this:

<div>
    <!-- where the php foreach would go -->
</div>

<div>
 <?= $name ?>
</div>

would this break the page? or are the variables local to anywhere after the foreach loop?

    Unlike Java and C++, variables declared inside blocks such as loops or if's, will also be recognized and accessible outside of the block. As written in PHP Manual.
