Question

我正在将XML文件转换为关联数组以提取数据，问题是我必须根据数组编号制作10个循环才能获取数据。

有没有更好的方法来获取特定的列数据而不创建许多循环？因为我想把它们分配给变量。

我试图从

获取数据的数组

我正试图获取这样的数据！

我有2个阵列“customer”和“customer1”

我想获得这样的数据

customer =＆gt;作者

输出

jack
jon

因为它们在客户数组中

它可以做到吗??

Answer 1

假设您的数组存储在$arr中，您将访问comp索引然后循环它，因为它们是数字索引。然后你有一个数组可以减少一些。这一切似乎有点膨胀的数组结构，但将工作

$arr; //Set this to your converted xml
$comps = $arr['catalog']['comp'];

foreach($comps as $comp){
    echo $comp['look']['shp']['wok']['group']['customer']['author'];
}
