本文介绍了如何在PHP中重新索引数组,但索引从1开始?的处理方法,对大家解决问题具有一定的参考价值,需要的朋友们下面随着小编来一起学习吧!
问题描述
我有以下数组,我想对其重新索引,以使键反转(理想情况是从1开始):
I have the following array, which I would like to reindex so the keys are reversed (ideally starting at 1):
当前数组(该数组实际上看起来像这样):
Current array (edit: the array actually looks like this):
Array (
[2] => Object
(
[title] => Section
[linked] => 1
)
[1] => Object
(
[title] => Sub-Section
[linked] => 1
)
[0] => Object
(
[title] => Sub-Sub-Section
[linked] =>
)
)
应该如何:
Array (
[1] => Object
(
[title] => Section
[linked] => 1
)
[2] => Object
(
[title] => Sub-Section
[linked] => 1
)
[3] => Object
(
[title] => Sub-Sub-Section
[linked] =>
)
)
推荐答案
如果要重新索引从零开始,只需执行以下操作:
If you want to re-index starting to zero, simply do the following:
$iZero = array_values($arr);
如果您需要从头开始,请使用以下命令:
If you need it to start at one, then use the following:
$iOne = array_combine(range(1, count($arr)), array_values($arr));
