Listing directory

[Pawe³ Ga³ecki]

I used following code to scan & list directory contents (including all
subdirectories). It turns out that subdirectories are NOT recognized as
directories when the function is called in a recursive way.
In other words when function scans a subdirectory no directories inside are
recognised as directories therefore it cannot scan ti's contents.

<?php
$directory = "/www/prawnik/";
function list_dir($dir) {
if ($handle = opendir($dir)) {
static $indent = 2;
echo "indent=$indent<br>";
echo "dir=$dir<br>";
while (false !== ($file = readdir($handle))) {
if ($file=="." || $file =="..") continue;
if (is_dir($file)=='dir') {
$indent++;
/*
for ($index=1; $index<=$indent; $index++) {
echo "&nbsp&nbsp";
};
*/
echo "<B>$file:".filetype($dir)."</B><br>";
$newdir = $dir.$file."/";
list_dir ($newdir);
$indent--;
} else echo "$indent:$file<br>";
}
closedir($handle);
}
}

list_dir ($directory);
?>
