如何从多维数组中获取父数组索引php

Question

我有一个数组$ arr。

当我打印它时，它显示如下结果。

Array

      [1] => Array 
       (
        [0] => product 
       ) 

     ) 
) 

，我有一个变量$ categ.For例如$ CATEG =“homeandgardenairconditioner型” 那么我想知道他的“名”父数组的索引是“homeandgardenairconditioner-键入“

即--- O/p应为9

如何得到这个指标。请帮我

感谢

Answer 1

可能重复，我认为你正在寻找这样的：

function getIndex($name, $array){ 
    foreach($array as $key => $value){ 
     if(is_array($value) && $value['name'] == $name) 
       return $key; 
    } 
    return null; 
} 

Answer 2

试试这个，

function find_parent($array, $needle, $parent = null) { 
    foreach ($array as $key => $value) { 
     if (is_array($value)) { 
      $pass = $parent; 
      if (is_string($key)) { 
       $pass = $key; 
      } 
      $found = find_parent($value, $needle, $pass); 
      if ($found !== false) { 
       return $found; 
      } 
     } else if ($key === 'id' && $value === $needle) { 
      return $parent; 
     } 
    } 

    return false; 
} 

$parentkey = find_parent($array, '0002');
