php array itetive visual parent>儿童 [英] php array iteration visually parent > child

问题描述

设法用childs创建数组树。看起来像这样。

managed to create array tree with childs. Looks like this.

想要尝试打印它具有相同的水平。

Want to try printing it out with same levels.

<ul>
<li>cat1</li>
<ul><li>sub-cat</li>
  <ul><li>subsub-cat</li>
    <ul><li>subsubsub-cat</li>
      <ul><li>subsubsubsub-cat</li></ul>
    <li>subcub-cat2</li>
<ul></ul></ul></ul></ul>
<li>cat2</li>
</ul>

需要使用迭代角度。至少指向正确的方向。

Need to use iterative angle. At least point me to to the right direction.

它不一定是UL LI，可以是 - 或某种类似，只需要使用迭代方法打印出来。

It doesn't have to be with UL LI, can be with -- -- or some sort similar, just need to print it out using iterative methods.

推荐答案

这不是确切的解决方案，但你可以使用这样的东西

It is not the exact solution but you can use something like this

foreach( $array as $item ){
    echo $item['id'].'<br>';
    while(isset($item['child'])){
        $item = $item['child'];
        echo $item['id'].'<br>';
    }
}
