使 PHP 数组很好地显示

Question

我想尝试让我的数组显示如下：

家长 |子 |子 | ...

下面是数组本质上，我正在尝试创建一个 csv（我可以创建 csv，但我无法找出筛选数组的每个元素以创建字符串的最佳方法）

[0] => Array
            (
                [id] => 79
                [parent_id] => 0
                [name] => Accessories
                [is_visible] => 1
                [url] => /bedroom-wear/accessories/
                [children] => Array
                    (

                            (

                                            )

                                    )

                            )

                    )

            )

期望的输出：

Accessories | Chokers
Accessories | Garters
Accessories | Gloves
Accessories | ...
Accessories | ...
Accessories | Pride | Confetti

我什至无法开始思考从哪里开始，如果有人能指出我正确的方向，那就太好了

好的，我已经把你见过的最简陋的 foreach 循环放在一起了，是的，我讨厌自己，但以防万一有人想要一种肮脏的方式来做到这一点：

foreach($response['data'] as $r){
  echo $r['name'] . "<br>";
  foreach($r['children'] as $child){
    echo $r['name'] . " | " . $child['name'] . "<br>";
    foreach($child['children'] as $a){
      echo $r['name'] . " | " . $child['name'] . " | " . $a['name'] . "<br>";
      foreach($a['children'] as $b){
        echo $r['name'] . " | " . $child['name'] . " | " . $a['name'] . " | " . $b['name'] . "<br>";
        foreach($b['children'] as $c){
          echo $r['name'] . " | " . $child['name'] . " | " . $a['name'] . " | " . $b['name'] . " | " . $c['name'] . "<br>";
          foreach($c['children'] as $d){
            echo $r['name'] . " | " . $child['name'] . " | " . $a['name'] . " | " . $b['name'] . " | " . $c['name'] . " | " . $d['name'] . "<br>";
          }
        }
      }
    }
  }
}

请记住，您必须为最大数量的子数组创建一个 foreach

输出：

Accessories
Accessories | Chokers
Accessories | Garters
Accessories | Gloves
Accessories | Masks
Accessories | Nipple Covers
Accessories | Pride
Accessories | Pride | Confetti
