你如何重新索引在PHP中的数组? [英] How do you reindex an array in PHP?
本文介绍了你如何重新索引在PHP中的数组?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
我有以下的数组,我想重新索引,以便键被逆转(最好从1开始):
当前阵列(修改的数组实际上看起来像这样):
阵列([2] =>目的
(
[标题] =>部分
[链接] => 1
)[1] =>目的
(
[标题] =>次节
[链接] => 1
)[0] =>目的
(
[标题] =>分次节
[链接] =>
))
就应该是这样:
阵列([1] =>目的
(
[标题] =>部分
[链接] => 1
)[2] =>目的
(
[标题] =>次节
[链接] => 1
)[3] =>目的
(
[标题] =>分次节
[链接] =>
))
解决方案
如果你想重新开始指数为零,只需做到以下几点:
$ iZero = array_values($ ARR);
如果你需要它的一个开始,然后使用下列内容:
$卓智= array_combine(范围(1,计数($ ARR)),array_values($ ARR));
下面是使用的函数的手册页:
I have the following array, which I would like to reindex so the keys are reversed (ideally starting at 1):
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] =>
)
)
How it should be:
Array (
[1] => Object
(
[title] => Section
[linked] => 1
)
[2] => Object
(
[title] => Sub-Section
[linked] => 1
)
[3] => Object
(
[title] => Sub-Sub-Section
[linked] =>
)
)
解决方案
If you want to re-index starting to zero, simply do the following:
$iZero = array_values($arr);
If you need it to start at one, then use the following:
$iOne = array_combine(range(1, count($arr)), array_values($arr));
Here are the manual pages for the functions used:
