php split array of strings to <ul><li> - php

Question

Hi I'm having the problem that I have an array list of strings which contains the path to .txt files on my server.
example:
// list all textfiles
$list = findFiles(dirname(__FILE__), array ("txt") );
// sort list
array_multisort($list["txt"], SORT_ASC, SORT_STRING );
// iterate through list and print out found files as ul-li list
foreach ($list["txt"] as $file_entry) {
echo '<li>$file_entry</li>\n';
}
This gets me something like that:
<li>path1\path\chek.txt</li>
<li>path1\path\test\check2.txt</li>
<li>path1\path1\test\check.txt</li>
<li>path2\test\pt\check1.txt</li>
<li>path2\test\pt\check2.txt</li>
<li>path2\test\check2.txt</li>
<li>path2\path2\check.txt</li>
<li>path2\path3\dir.txt</li>
<li>path2\path3\test\check.txt</li>
<li>path3\path3\test\check1.txt</li>
I want to "convert" that array to something which looks like an directory tree (to make later use of some jquery plugin [e.g. http://filamentgroup.com/examples/jquery-tree-control/] ):
<ul>
<li>path1
<ul>
<li>path</li>
<ul>
<li>check.txt</li>
</ul>
<li>path1</li>
...
So the question is how to make such a directory list from my array?

Here's what I got, by transforming the paths into nested arrays, then merging them recursively, then formatting using a recursive function to print it out as a list;
$list['txt'] = array(
'path1\path\chek.txt',
'path1\path\test\check2.txt',
'path1\path1\test\check.txt',
'path2\test\pt\check1.txt',
'path2\test\pt\check2.txt',
'path2\test\check2.txt',
'path2\path2\check.txt',
'path2\path3\dir.txt',
'path2\path3\test\check.txt',
'path3\path3\test\check1.txt'
);
$paths = array();
foreach ($list['txt'] as $file_entry) {
$path = explode('\\', $file_entry);
$pathArr = $file_entry;
for ($i = count($path) - 1; $i >= 0; $i--) {
$pathArr = array($path[$i] => $pathArr);
}
$paths = array_merge_recursive($paths, $pathArr);
}
function to_list($paths, $depth = 0) {
echo str_repeat("\t", $depth) . "<ul>\n";
foreach ($paths as $entry => $value) {
echo str_repeat("\t", $depth + 1) . '<li>';
if (is_array($value)) {
echo "$entry\n";
to_list($value, $depth + 2);
echo "\n" . str_repeat("\t", $depth + 1);
} else {
echo "$entry";
}
echo "</li>\n";
}
echo str_repeat("\t", $depth) . "</ul>\n";
}
to_list($paths);

I think that you should better "explode" every string to an array() using "\" as delimiter, than you merge all table ton one multi-array.
['path1']=>['path']=>"chek.txt"
=>['path']=>['test']=>"check2.txt"
=>['path']=>['test']=>"check.txt"
...
finaly for every new array you add an "<ul>" tag !
