php - 如何将一维数组转换为二维数组

Question

我有以下数组，来自一个表单，包含这样的多语言数据:

Array
(
    [en_name] => ...........
    [en_description] => ...........
    [gr_name] => ...........
    [gr_description] => ...........
)

如何将这个数组转换成二维的:

Array
(
    [en] => Array
        (
            [name] => ...........
            [description] => ...........
        )

    [gr] => Array
        (
            [name] => ...........
            [description] => ...........
        )
)

Answer 1

使用这段代码:

$finalArr = array();
foreach($arr as $key => $val) {
   $tok = explode('_', $key);
   $finalArr[$tok[0]][$tok[1]] = $val;
}
