我有一个目录,子目录和文件树(在一些但不是所有目录中)。这是整棵树的一个例子:
/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
好的,从'/'目录中的php脚本,我想递归或遍历这个目录树并打印这样的树:
<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>
<li>red.html</li>
<li>pink.html</li>
<li>purple.html</li>
</ul>
</ul>
</ul>
</ul>

我认为您需要的是RecursiveDirectoryIterator
中的PHP Standard Library (SPL)然后你可以写下类似的东西:
function iterateDirectory($i)
{
echo '<ul>';
foreach ($i as $path) {
if ($path->isDir())
{
echo '<li>';
iterateDirectory($path);
echo '</li>';
}
else
{
echo '<li>'.$path.'</li>';
}
}
echo '</ul>';
}
$dir = '/food';
$iterator = new RecursiveIteratorIterator(new RecursiveDirectoryIterator($dir));
iterateDirectory($iterator);

要开始使用,需要使用以下功能:
要将它们粘合在一起,您需要:
for
,for each
,while
)以上是在粘贴上述所有资源之后的情况:
<?php
function read_dir_content($parent_dir, $depth = 0){
$str_result = "";
$str_result .= "<li>". dirname($parent_dir) ."</li>";
$str_result .= "<ul>";
if ($handle = opendir($parent_dir))
{
while (false !== ($file = readdir($handle)))
{
if(in_array($file, array('.', '..'))) continue;
if( is_dir($parent_dir . "/" . $file) ){
$str_result .= "<li>" . read_dir_content($parent_dir . "/" . $file, $depth++) . "</li>";
}
$str_result .= "<li>{$file}</li>";
}
closedir($handle);
}
$str_result .= "</ul>";
return $str_result;
}
echo "<ul>".read_dir_content("d:/movies/")."</ul>";

我用它来拥有目录中的所有文件:
function tree($path, $exclude = array()) {
$files = array();
foreach (new RecursiveIteratorIterator(new RecursiveDirectoryIterator($path)) as $splfileinfo) {
if (!in_array(basename($splfileinfo), $exclude)) {
$files[] = str_replace($path, '', '' . $splfileinfo);
}
}
return $files;
}

希望此功能可以帮助您完成工作。
/*
* Retern the file list which include in the given directory
*
* @param String $dirpath : Path to the directory
*
* @access public
*
* @return Array
*/
function getFileList($dirpath)
{
$filelist = array();
if ($handle = opendir(dirname ($dirpath)))
{
while (false !== ($file = readdir($handle)))
{
$filelist[] = $file;
}
closedir($handle);
}
return $filelist;
}
