如何從多維數組中提取特定的關鍵數據
[英]How to pull a specific key data from multidimensional array
問題描述
我正在將XML文件轉換為關聯數組以提取數據，問題是我必須根據數組編號進行10次循環才能獲取數據。
有沒有更好的方法來獲取特定的列數據而不創建很多循環？ 因為我想將它們分配給變量。
我試圖從中獲取數據的數組
Array
(
[catalog] => Array
(
[comp] => Array
(
[0] => Array
(
[look] => Array
(
[shp] => Array
(
[wok] => Array
(
[group] => Array
(
[customer] => Array
(
[author] => jack
[title] => Midnight Rain1
[genre] => Fantasy
[price] => 5.95
[publish_date] => 2000-12-16
[description] => A former architect battles corporate zombies.
)
[customer2] => Array
(
[author] => lemass
[title] => Midnight Rain1
[genre] => Fantasy
[price] => 5.95
[publish_date] => 2000-12-16
[description] => A former architect battles corporate zombies.
)
)

)
)
[1] => Array
(
[look] => Array
(
[shp] => Array
(
[wok] => Array
(
[group] => Array
(
[customer] => Array
(
[author] => jon
[title] => Midnight Rain1
[genre] => Fantasy
[price] => 5.95
[publish_date] => 2000-12-16
[description] => A former architect battles corporate zombies.

[customer2] => Array

我正在嘗試獲取這樣的數據！
我有2個數組“ customer”和“ customer1”
我想要這樣的數據
客戶=>作者
輸出
jack
jon
因為它們在客戶群中
它有可能做到這一點？

假設您的數組存儲在$arr您將訪問comp索引，然后對其進行循環，因為它們是數字索引。 然后，您有一個陣列可以減少更多內容。 數組結構似乎使這一切膨脹了，但可以正常工作
$arr; //Set this to your converted xml
$comps = $arr['catalog']['comp'];
foreach($comps as $comp){
echo $comp['look']['shp']['wok']['group']['customer']['author'];
}
