如何通过多维数组获取类别级别php

如何动态获取类别级数。这是一个PHP数组，当用户改变菜单结构时，这可能会改变，但目前这是一个结构，我只是想知道邮件类别和主类别中多少级别的子类别是“品牌”。这是我的数组结构。如何通过多维数组获取类别级别php

你的问题不明确正是你期待什么。 – kazinayem2011

看看我的阵列结构，你会看到主阵列是品牌和水平是（1）和内部品牌 - >服装哪些级别是（2）和内部品牌 - >服装 - >阿迪达斯哪个级别是（3）这是我究竟想要什么。我想知道邮件类别中的子类别的级别。 –

您可以递归做到这一点：

function countChildren($array) { 
     $children = 0; 
     if (isset($array["children"]) { 
      $children = count($array["children"]); 
      foreach ($array["children"] as $subarray) { 
       $children += countChildren($subarray); 
      } 
     } 
     return $children;   
}

仅计算你能做的水平：

function countChildrenLevels($array) { 
     $children = 0; 
     if (isset($array["children"]) {     
      $sublevels = []; 
      foreach ($array["children"] as $subarray) { 
       $sublevels[] = countChildren($subarray); 
      } 
      $children = 1 + max($sublevels); 
     } 
     return $children;   
}
