如何在 PHP 中重新索引数组但索引从 1 开始? [英] How do you reindex an array in PHP but with indexes starting from 1?

问题描述

我有以下数组，我想对其重新索引，以便反转键(理想情况下从 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(数组实际上是这样的):

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

如果您想从零开始重新索引，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);

如果您需要从一个开始，请使用以下内容:

If you need it to start at one, then use the following:

$iOne = array_combine(range(1, count($arr)), array_values($arr));

以下是所用函数的手册页:

Here are the manual pages for the functions used:

• array_values()
• array_combine()
• range()
