PHP遍历数组并拆分为单独的数组

Question

嗨，我有这个PHP的Amazon Sub Categories数组，我想做的是遍历该数组并分成3个单独的数组，

这里是数组，需要分成3个数组$ request和它下面的所有子元素$ subCats和最终变量$ Ancestors。 $ subCats将包含所有的[Children] [BrowseNode]。 它让我发疯，我似乎无法正确地通过。

任何想法的人。 欢呼雀跃。

Answer 1

应该这样做：

$request = your_main_array['request'];
$subCats = your_main_array['BrowseNode']['Children']['BrowseNode'];
$Ancestors = your_main_array['BrowseNode']['Ancestors']

['Children'] ['BrowseNode']和['Ancestors']位于主数组下的[BrowseNode]数组中。
