Listing Files And folders?

[Anon]

OKay I have a snippet of code that looks really nice except when i actually execute it I end up with a blank page instead of the recursive dir's That should be expected.

ANy ideas what could be wrong here?
<?

function browse_dir($dir_name, $spaces = 0){
$dir = opendir($dir_name);
while($file = readdir($dir)){
if($file != "." && $file != "..")
if(is_dir($dir_name . $file))
$found_dirs[] = $file;
else
$found_files[] = $file;
}
closedir($dir);

for($j = 0; $j < $spaces; $j++)
echo "&nbsp;&nbsp;";

if($found_dirs || $found_files)
echo "<img src=open.gif>&nbsp;" . basename($dir_name) . "<br>\n";
else
echo "<img src=closed.gif>&nbsp;" . basename($dir_name) . "<br>\n";

if($found_dirs){
sort($found_dirs);
for($i = 0; $i < count($found_dirs); $i++)
if($found_dirs[$i] != "." && $found_dirs[$i] != "..")
browse_dir($dir_name . $found_dirs[$i] . "/", $spaces + 1);
}

if($found_files){
sort($found_files);
for($i = 0; $i < count($found_files); $i++){
for($j = 0; $j < $spaces + 1; $j++)
echo "&nbsp;&nbsp;";
echo "<img src=file.gif>&nbsp;$found_files[$i]<br>\n";
}
}

}

?>
Thnx for any help :-)

This worked for me to list all dirs and files:

<?PHP
$handle = opendir("C:/path_to_dir");
$i=0;
// the while loop and sort are just nice
// to have, to get the results in
// alphabetic order
while(($object = readdir($handle))!=false) {
$items[$i] = $object;
$i++;
}
sort($items);
foreach($items as $object) {
print("<br>".$object);
}
closedir($handle);
?>

Well yeah but i need a few of the functions that are in this other code to display the Items in a Table properly.
Any idea why the code i posted wouldnt work?

You should read the section on "Variable Scope" in the PHP documentation, and/or get a book that explains Variable Scope. You've got some serious problems there...

I'd tell you the answer, but I'd prefer you research it yourself, because Variable scope is a very important issue in programming. You can use it for your benefit, but it can also lead to serious bugs if you don't understand the topic fully.
