Php 将每个子密钥包装在UL中

我想将每个子数组封装在一个

中，但我不完全确定该如何实现

function RecursiveWrite($array) {
    foreach ($array as $v) {

        echo '<li>';

            echo $v['id'];

            if(isset($v['children']))
                RecursiveWrite($v['children']);

        echo '</li>';

    }
}

echo '<ul>';
RecursiveWrite($comments);
echo '</ul>';

---

看起来您只需要在foreach循环前后回显

标记

简单到

function RecursiveWrite($array) {
    echo "<ul>";
    foreach ($array as $v) {
        ...
    }
    echo "</ul>";
}

RecursiveWrite($comments);

函数递归写入（$array）{
回声“
”；
foreach（$v数组）{
...
}
回声“
”；
}
递归写入（$comments）；

你不能在数组循环前后重复一下吗？@卓别林不必觉得自己很愚蠢：）即使你的问题确实很简单，但你确实表现出了一些努力，仅此一点就比现在提出的至少60%的问题要好。继续努力，再见；）
