移动阵列中的一个关联数组键 [英] Move an associative array key within an array
本文介绍了移动阵列中的一个关联数组键的处理方法,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
我怎么能在一个阵列移动的副项,以便它是另一个指定的键后?
例如, $列
的电流输出如下 -
$列=阵列(
[标题] =>标题
[作者] =>作者
[分类法news_type] =>新闻类型
[日期] =>日期
[wpseo得分=>搜索引擎优化
[P2P-从-news_to_people] =>工作人员联系到这个故事
[show_item_ids] => ID
)
一种情况是,我想移动的关键 P2P-从-news_to_people
直接后分类法news_type
,生产这种输出 -
$列=阵列(
[标题] =>标题
[作者] =>作者
[分类法news_type] =>新闻类型
[P2P-从-news_to_people] =>工作人员联系到这个故事
[日期] =>日期
[wpseo得分=>搜索引擎优化
[show_item_ids] => ID
)
解决方案
您可以创建一个自定义功能的特定按键后插入一个新的项目:
函数array_insert_after($数组$ findAfter,$键,$新)
{
$ POS =(INT)array_search($ findAfter,array_keys($阵列))+ 1;
返回array_merge(
array_slice($阵列,0,$ POS),
阵列($关键=> $新)
array_slice($数组$ POS)
);
}
用法:
$ ELEM = $改编['P2P - 从 - news_to_people']; //存储值
未设置($改编['P2P - 从 - news_to_people']); //取消设置VAR$ ARR = array_insert_after(
$ ARR,/ *原始数组* /
分类学news_type',/ *项目之后,ELEM应插入* /
P2P-从-news_to_people',/ *的* ELEM关键/
$ ELEM / *的* ELEM的价值/
);的print_r($ ARR);
输出:
阵列
(
[标题] =>标题
[作者] =>作者
[分类法news_type] =>新闻类型
[P2P-从-news_to_people] =>工作人员联系到这个故事
[日期] =>日期
[wpseo得分=>搜索引擎优化
[show_item_ids] => ID
)
How can I move an associate key in an array so that it is after another specified key?
For example, the current output of $columns
is as follows -
$columns = Array(
[title] => Title
[author] => Author
[taxonomy-news_type] => News Types
[date] => Date
[wpseo-score] => SEO
[p2p-from-news_to_people] => Staff linked to this Story
[show_item_ids] => ID
)
One scenario is that I would like to move the key p2p-from-news_to_people
to directly after taxonomy-news_type
, producing this output -
$columns = Array(
[title] => Title
[author] => Author
[taxonomy-news_type] => News Types
[p2p-from-news_to_people] => Staff linked to this Story
[date] => Date
[wpseo-score] => SEO
[show_item_ids] => ID
)
解决方案
You can build a custom function to insert a new item after a specific key:
function array_insert_after($array, $findAfter, $key, $new)
{
$pos = (int) array_search($findAfter, array_keys($array)) + 1;
return array_merge(
array_slice($array, 0, $pos),
array($key => $new),
array_slice($array, $pos)
);
}
Usage:
$elem = $arr['p2p-from-news_to_people']; // store the value
unset($arr['p2p-from-news_to_people']); // unset the var
$arr = array_insert_after(
$arr, /* original array */
'taxonomy-news_type', /* item after which the elem should be inserted */
'p2p-from-news_to_people', /* key of the elem */
$elem /* the value of the elem */
);
print_r($arr);
Output:
Array
(
[title] => Title
[author] => Author
[taxonomy-news_type] => News Types
[p2p-from-news_to_people] => Staff linked to this Story
[date] => Date
[wpseo-score] => SEO
[show_item_ids] => ID
)
