php - 从多级多维数组中提取名称

Question

我有多维数组。它可以扩展到N级。我只想收集名字。从孩子到父母的名字。例如我需要这样的输出

名称 => “Sport/Algemeen/techn.sp.ondgd/ondergoed dames/Sport bh”

. 级别最多可以创建 N 个数字。

   [categories] => Array
            (
                [0] => Array
                    (
                        [@id] => 1
                        [name] => 78057 | Sport bh
                        [parent] => Array
                            (
                                [@id] => 2
                                [name] => 7805 | ondergoed dames
                                [parent] => Array

                                        [@id] => 3
                                        [name] => 780 | techn.sp.ondgd

Answer 1

像这样（尚未测试）

function namify($arr) {
    foreach($arr as $cat) {
        if(!empty($cat['parent']) && is_array($cat['parent'])) {
            return $cat['name'].namify($cat['parent']);
        } else {
            return $cat['name'];
        }
    }
}

echo namify($categories);

Answer 2

$arrPush = array();
function iterator($arr){
    global $arrPush;
    foreach($arr as $key => $val){
        if(is_array($val))
            iterator($val);
        if($key == "name"){
            $str = explode("|", $val);
            $arrPush[] =  isset($str[1])?$str[1]:$str[0];
        }
        //filter the $key and $val here and do what you want
    }
}
iterator($sweet);
$str = implode("/", array_reverse($arrPush));
echo $str;

Sport/Algemeen/ techn.sp.ondgd/ ondergoed dames/ Sport bh
