PHP将一维数组转换为多维数组 [英] PHP convert one dimensional array into multidimensional

问题描述

我有一个数组

$tmpArr =  array('A', 'B', 'C');

我要处理此数组，并希望将新数组设为

I want to process this array and want new array as

$tmpArr[A][B][C] = C

即最后一个元素成为最终数组的值.

I.e last element becomes the value of final array.

有人可以建议解决方案吗?请帮忙.预先感谢

Can anyone suggest the solution? Please help. Thanks in advance

推荐答案

迭代键数组并使用引用表示链的末尾:

Iterate the array of keys and use a reference for the end of the chain:

$arr = array();
$ref = &$arr;
foreach ($tmpArr as $key) {
    $ref[$key] = array();
    $ref = &$ref[$key];
}
$ref = $key;
$tmpArr = $arr;
