这是我的 php 脚本:
<?php
$path = $_SERVER['DOCUMENT_ROOT'].'/test';
$objects = new RecursiveIteratorIterator(new RecursiveDirectoryIterator($path), RecursiveIteratorIterator::SELF_FIRST);
foreach($objects as $name => $object){
echo $objects->getDepth() . " " . $object->getFilename() . "<br/>";
}
?>
这是脚本正在迭代的目录/文件树。(它位于一个名为 $_SERVER['DOCUMENT_ROOT'].'/test' 的普通根目录中):
/food
/food/drinks
/food/drinks/water.html
/food/drinks/milk.html
/food/drinks/soda.html
/food/entrees
/food/entrees/hot
/food/entrees/hot/hamburger.html
/food/entrees/hot/pizza.html
/food/entrees/cold
/food/entrees/cold/icecream.html
/food/entrees/cold/salad.html
/cosmetics
/cosmetics/perfume
/cosmetics/perfume/chic.html
/cosmetics/perfume/polo.html
/cosmetics/perfume/lust.html
/cosmetics/lipstick
/cosmetics/lipstick/colors
/cosmetics/lipstick/colors/red.html
/cosmetics/lipstick/colors/pink.html
/cosmetics/lipstick/colors/purple.html
这是脚本输出的内容:
0 food
1 drinks
2 milk.html
2 water.html
2 soda.html
1 info.php
1 entrees
2 hot
3 pizza.html
3 hamburger.html
2 cold
3 ice_cream.html
3 salad.html
0 cosmetics
1 lipstick
2 colors
3 pink.html
3 red.html
3 purple.html
1 perfume
2 polo.html
2 lust.html
2 chic.html
0 error_log
0 test.php
忽略 $objects->getDepth() 整数;仅供参考
问题:如何修改我的脚本以输出嵌套的无序列表,如下所示:
<ul>
<li>food</li>
<ul>
<li>drinks</li>
<ul>
<li>water.html</li>
<li>milk.html</li>
<li>soda.html</li>
</ul>
<li>entrees</li>
<ul>
<li>hot</li>
<ul>
<li>hamburger.html</li>
<li>pizza.html</li>
</ul>
<li>cold</li>
<ul>
<li>icecream.html</li>
<li>salad.html</li>
</ul>
</ul>
</ul>
<li>cosmetics</li>
<ul>
<li>perfume</li>
<ul>
<li>chic.html</li>
<li>polo.html</li>
<li>lust.html</li>
</ul>
<li>lipstick</li>
<ul>
<li>colors</li>
<ul>
谢谢!
