PHP - 从分隔的字符串进行多维关联数组 [英] PHP - Make multi-dimensional associative array from a delimited string

问题描述

您可以把这个字符串：

"package.deal.category"

到像这样的数组：

Into an array like this:

$array['package']['deal']['category']

此时索引内的值可以是任何东西。

The value inside the index at this point can be anything.

推荐答案

你尝试过什么？绝对的答案，这是很容易的：

What have you tried? The absolute answer to this is very easy:

$keys = explode('.', $string);
$array = array();
$arr = &$array;
foreach ($keys as $key) {
   $arr[$key] = array();
   $arr = &$arr[$key];
}
unset($arr);
