Answer 1

<?php 
function recursive_array_search($needle,$haystack) { 
    foreach($haystack as $key=>$value) { 
     $current_key=$key; 
     if($needle===$value OR (is_array($value) && recursive_array_search($needle,$value) !== false)) { 
      return $current_key; 
     } 
    } 
    return false; 
}

试试这个。

function search_id($array, $id) 
    foreach ($array['items'] as $key => $val) { 
     foreach($val['option_value'] as $option_key => $option_value) 
     { 
      if ($option_value['option_value_id'] == $id) 
      { 
       return $option_key; 
      } 
     } 
    }
