PHP - 从分隔字符串制作多维关联数组 [英] PHP - Make multi-dimensional associative array from a delimited string

问题描述

你能把这个字符串转过来吗:

Can you turn this string:

"package.deal.category"

变成这样的数组:

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

此时索引内的值可以是任何值.

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

推荐答案

您尝试了什么?对此的绝对答案非常简单:

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);

...但是为什么这对你有用?
