我有一个 PHP 多维数组(如下)。
Array
(
[0] => Array
(
[2] => one@example.com
)
[1] => Array
(
[4] => two@example.com
)
[2] => Array
(
[3908] => twenty@example.com
)
[3] => Array
(
[2548] => eleven@example.com
)
[4] => Array
(
[3099] => ten@example.com
)
[5] => Array
(
[5283] => six@example.com
)
)
我想知道如何使用PHP进行合并或组合,或者像下面这样简单地完成。
Array
(
[2] => one@example.com
[4] => two@example.com
[3908] => twenty@example.com
[2548] => eleven@example.com
[3099] => ten@example.com
[5283] => six@example.com
)
