PHP - 是在foreach循环本地的foreach循环中定义的变量吗?
问题描述:
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?
答
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.
