如何使用键位置访问关联数组？

Let's say I have this code:

假设我有这个代码：

    $games = [
    "Boys" => ["Danny", "Ben"],
    "Girls" => ["Ashley", "Sandra"]
];

And for example, I want to access Danny's name. I can access it by using

例如，我想访问Danny的名字。我可以通过使用来访问它

$games["Boys"][0]

But what if I want to access it by it's bit index (for future foreach loops)? I tried something like:

但是如果我想通过它的位索引（对于未来的foreach循环）来访问它呢？我试过类似的东西：

 $games[0][0]

But I get an error (unindexed something).

但我得到一个错误（没有索引的东西）。

1 个解决方案

#1

Use array_values to create a numerical array from $games, then index that:

使用array_values从$ games创建一个数值数组，然后索引：

echo array_values($games)[0][0];

Hope that helps
