有人可以帮我创建一个递归函数，在列表中打印出这个数组ul＆gt; li＆gt; ul.children等等。谢谢！ ：）

这会使<ul>任意深入。每个<ul>都有一个level#类，其中#是一个从顶层开始的整数。
function make_list($array, $level = 0)
{
$ret = "<ul class=\"level$level\">";
foreach($array as $sub)
{
if(is_array($sub))
{
$sub = make_list($sub, $level + 1);
}
$ret .= "\n<li>$sub</li>";
}
$ret .= "\n</ul>";
return $ret;
}
假设您的原始数组名为$my_array，您可以这样调用它：
echo make_list($my_array);

只需创建一个显示一个级别的功能。每次遇到子数组时，都会在该子数组上递归调用该函数。每次调用函数之前和之后都要写ul标记。
