循环多维数组并删除某些键

我有一个基于下面数组的嵌套树结构：

Array
(
    [1] => Array
        (
            [id] => 1
            [parent] => 0
            [name] => Startpage
            [uri] => 125
            [basename] => index.php
            [child] => 
        )

    [23] => Array
        (
            [id] => 23
            [parent] => 0
            [name] => Events
            [uri] => 0
            [basename] => 
            [child] => Array
                (
                    [24] => Array
                        (
                            [id] => 24
                            [parent] => 23
                            [name] => Public news
                            [uri] => 0
                            [basename] => 
                            [child] => Array

                                        )

                                )

                                            [uri] => 70
                                            [basename] => news.event.overview.php
                                            [child] => 
                                        )

                                )

                        )

                )

        )
)  

我正在寻找一个函数来循环（递归？）数组并删除一些键。

在我的系统中，我可以允许用户访问某些功能/页面，如果我拒绝访问整个“块”“事件”，则数组将如下所示：

array (
  1 => 
  array (
    'id' => '1',
    'parent' => '0',
    'name' => 'Start page',
    'uri' => '125',
    'basename' => 'index.php',
    'child' => '',
  ),
  23 => 
  array (
    'id' => '23',
    'parent' => '0',
    'name' => 'Events',
    'uri' => '0',
    'basename' => NULL,
    'child' => 
    array (
      24 => 
      array (
        'id' => '24',
        'parent' => '23',
        'name' => 'Public news',
        'uri' => '0',
        'basename' => NULL,
        'child' => '',
      ),
      25 => 
      array (
        'id' => '25',
        'parent' => '23',
        'name' => 'Private news',
        'uri' => '0',
        'basename' => NULL,
        'child' => '',
      ),
      26 => 
      array (
        'id' => '26',
        'parent' => '23',
        'name' => 'Calendar',
        'uri' => '0',
        'basename' => NULL,
        'child' => '',
      ),
    ),
  )
)  

正如您在上面看到的，整个“块”“事件”现在毫无用处，因为没有与每个选项关联的页面。因此，我需要找到“basename”为空且 child 不是数组或数组为空的所有“键”并删除它们。 我在搜索网站时发现了这个功能：

function searchAndDestroy(&$a, $key, $val){
    foreach($a as $k => &$v){
        if(is_array($v)){
            $r = searchAndDestroy($v, $key, $val);
            if($r) {
                unset($a[$k]);
            }
        } elseif ($key == $k && $val == $v) {
            return true;
        }
    }
    return false;
}

它可用于删除数组中任何位置的键，但仅基于一件事，例如删除“parent”等于“23”的所有键。但我需要找到并删除（取消设置）“basename”为空且 child 不是数组或数组为空的所有键。 任何人都可以帮助我并可能调整上面的功能吗？

谢谢你，

不要在搜索函数中测试要销毁哪些元素，而是传递一个函数来测试目标。

function searchAndDestroy(&$a, $targetp){
    foreach($a as $k => &$v){
        if(is_array($v)){
            searchAndDestroy($v, $targetp);
        } 
        if ($targetp($k, $v)) {
            unset($a[$k]);
        }
    }
}

searchAndDestroy($menu, function ($k, $v) {
        return is_array($v) 
            && array_key_exists('basename', $v) && empty($v['basename'])
            && (empty($v['child']) || count($v['child']) == 0);
    });

对于 PHP searchAndDestroy该函数位于多个位置），命名该函数并传递该名称而不是匿名函数。
