从多维数组中获取特定的关键数据

Question

我将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。

我尝试从

获取数据的数组

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

                )
              )
            )
          )
        )
      )
      [1] => Array
      (
        [look] => Array
        (
          [shp] => Array
          (
            [wok] => Array
            (

              (
                [customer] => Array
                (
                  [author] => jon
                  [title] => Midnight Rain1
                  [genre] => Fantasy

                  [description] => A former architect battles corporate zombies.
                )

                )
              )
            )
          )
        )
      )
    )
  )
)

我试图获取这样的数据。

我有2个数组customer和customer1

我想获得这样的数据

customer => author

输出

jack
jon

因为它们位于customer数组

中

有可能吗？

Answer 1

 $comps = $arr['Shp']['test'];
 foreach ($comps  as $comp) {
 if (is_array($comp))
 echo $comp['Shp2'] ['customer'] ['address'] ['ad1']; } 
 or use this echo $comp['test'] ['Shp2'] ['customer'] ['address'] ['ad1'];
