如何从关键元素获取层次结构并基于此创建新元素 - PHP
How to get hyrarchy from key elements and create new elements based on that - PHP
我有一个很大的数组,我会尝试用小例子来解释这个问题:
输入:
Array (
[alert:accountDisabled:heading] => XYZ
[alert:accountDisabled:message] => XYZ
[alert:accountExpired:heading] => XYZ
[alert:accountExpired:message] => XYZ
[alert:errorResponse:heading] => XYZ
[button:back] => XYZ
)
我需要得到的是:
array() {
["alert"]=> array(7) {
["accountDisabled"]=> array(2) {
["heading"]=> string(3) "XYZ"
["message"]=> string(3) "XYZ" }
["accountExpired"]=> array(2) {
["heading"]=> string(3) "XYZ"
["message"]=> string(3) "XYZ" }
["clientError"]=> array(2) {
["heading"]=> string(3) "XYZ"
["message"]=> string(3) "XYZ" }
["errorResponse"]=> array(1) {
["heading"]=> string(3) "XYZ" }
}
["button"]=> array(1) {
["back"]=> string(3) "XYZ"
}
正如我所说,这是一个非常小的例子,但重点是从数组一的键中获取层次结构,层次结构除以键中的这个字符 :
我检查了那些看起来与此类似的问题,但它们根本没有帮助
Using a string path to set nested array data
所以请仔细阅读我的问题描述。
我尝试将它用于每个循环,并且成功地将元素从键中划分为一个元素,但我不确定我需要在哪里存储下一个元素的层次结构值,有什么想法吗?
$input = [
'alert:accountDisabled:heading' => 'XYZ_1',
'alert:accountDisabled:message' => 'XYZ_2',
'alert:accountExpired:heading' => 'XYZ_3',
'alert:accountExpired:message' => 'XYZ_4',
'alert:errorResponse:heading' => 'XYZ_5',
'button:back' => 'XYZ_6'
];
$results = [];
foreach ($input as $key => $value) {
$arr = explode(':', $key);
$result = $value;
for ($i = count($arr) - 1; $i >= 0; $i--) {
$result = [ $arr[$i] => $result ];
}
$results[] = $result;
}
$result = array_merge_recursive(...$results);
print_r($result);
输出:
Array
(
[alert] => Array
(
[accountDisabled] => Array
(
[heading] => XYZ_1
[message] => XYZ_2
)
[accountExpired] => Array
(
[heading] => XYZ_3
[message] => XYZ_4
)
[errorResponse] => Array
(
[heading] => XYZ_5
)
)
[button] => Array
(
[back] => XYZ_6
)
)
根据Lukas.j回答,你可以使用这个函数:
function parsePath($array, $separator = ':'){
$result = [];
foreach($array as $key => $value){
if(strpos($key, $separator) !== FALSE){
$keys = explode($separator, $key);
$inner_result = $value;
foreach (array_reverse($keys) as $valueAsKey) $inner_result = [$valueAsKey => $inner_result];
$result[] = $inner_result;
}
}
return array_merge_recursive(...$result);
}
