如何压平多维数组递归php。 我试过这个link的代码，但没有工作。我也尝试了许多其他的链接，但没有工作。 This代码已用于创建此数组。压扁多维数组递归php

public function downline_income($userId = null, $offset = 0) { 
    $userId = user::id(); 
    $limit = AZ::setting('record_per_page'); 
    $objUser = new stdClass(); 
    $objUser->id = $userId; 
    $downline = $this->user->getDownline($objUser); 

    AZ::layout('left-content', array(
     'block' => 'account/downline_income', 
     'user' => $userId, 
     'total_users' => $total_users, 
     'pagination' => $pagination, 
     'q' => $userId, 
     'data' => $downline, 
     'offset' => $offset, 
    )); 
} 

public function getDownline($obj, $level = 0) { 
    $obj->level = $level; 

    $where = array('parent_id' => $obj->id); 
    $this->db->select('users.*'); 
    $this->db->where($where); 

    $query = $this->db->get('users')->result(); 

    foreach ($query as $objUser) { 
     $obj->data[] = $this->getDownline($objUser, ($level + 1)); 
    } 

    return $obj; 
}

这里是我需要压平的数组。

我试着用下面的代码，但它的工作只有2级

public function array_flatten($array, $i = 0) { 
    $flat = array(); 

    foreach ($array as $value) { 
     if (isset($value->data) && is_array($value->data)) { 
      $flat = array_merge($flat, $this->array_flatten($value->data)); 
     } else { 
      $flat[] = $value; 
     } 
    } 
    return $flat; 
}

欲望输出

我不知道你为什么要做这个复杂的消光，我敢肯定，你可以 - as it's seems that you are fetching data from database - 你可以做到这一点更容易，下面的方法，但是，您可能需要使用递归在这里，例如：

// Sample data 
$arr = [ 
    ['level' => 1, 'data' => [['level' => 2],['level' => 3, 'data' => [['level' => 6]]]]], 
    ['level' => 4], 
    ['level' => 9, 'data' => [['level' => 8]]], 
]; 

function flat($data, &$list = []) 
{ 
    foreach ($data as $key => $value) { 
     if (isset($value['data']) && is_array($value['data'])) { 
      $tmp = $value['data']; 
      unset($value['data']); 
      flat($tmp, $list); 
     } 
     $list[] = $value; 
    } 
    return $list; 
} 

print_r(flat($arr));

PS往往递归是大阵列更加昂贵
