我有一个问题，我必须使10个循环取决于数组编号才能获得数据。
我通过其他帖子的帮助解决了这个问题，但我有一个问题重命名
我正在使用的数组
Array
(
[catalog] => Array
(
[book] => Array
(
[0] => Array
(
[took] => Array
(
[dodo] => Array
(
[ahmadz] => Array
(
[lolo] => Array
(
[tata] => Array
(
[author] => ahmadz
[title] => Midnight Rain
[genre] => Fantasy
[price] => 5.95
[publish_date] => 2000-12-16
[description] => A former architect battles corporate zombies,
an evil sorceress, and her own childhood to become queen
of the world.

)
[1] => Array
(
[took] => Array
(
[dodo] => Array
(
[ahmadz] => Array
(
[lolo] => Array
(
[tata2] => Array
(
[author] => Ralls, Kim
[title] => Midnight Rain
[genre] => Fantasy
[price] => 5.95
[publish_date] => 2000-12-16

这就是我如何从中获取特定数据
$author_array = array();
array_walk_recursive($array, function($value, $key) {
if (in_array($key, array("author"))) {
echo $author_array[] = $value;
}
});
在这些值之前我遇到的问题
[author] => ahmadz
[title] => Midnight Rain
[genre] => Fantasy
[price] => 5.95
我有不同的钥匙
tata和tata2
我想只获取“tata”键中的值
但上面的代码从“tata”和“tata2”键返回两个值
请帮我从一个键中获取数据而不是两个

这是一个草率的方法，但它应该工作。只需查找tata密钥，然后从中提取作者字段。
$author_array = array();
array_walk_recursive($array, function($value, $key) {
if (in_array($key, array("tata"))) {
echo $author_array[] = $value["author"];
}
});

只需使用嵌套的foreach循环
foreach（$ array [“catalog”] [“book”] as $ key =＆gt; $ value）{foreach（$ value [“took”] [“dodo”] [“ahmadz”] [“lolo” ] as $ key2 =＆gt; $ value2）{echo“author：”。 $ 2 [ “作者”];}}
