List all folders in directory (PHP)

Question

How can I make my code only display links to the folders and not the files in the directory?

$d = dir(".");
echo "<ul>";
while(false !== ($entry = $d->read())) {
    echo "<li><a href='{$entry}'>{$entry}</a></li>";
}
echo "</ul>";
$d->close();

$arr = scandir('dirname'); then loop $arr and test is_dir($item) — halojoy, Dec 27 '17 at 21:28

Looking for a much better generalized answer to this for arbitrary directories, returns an array, and can be recursive? See https://stackoverflow.com/a/61168906/430062 — Theodore R. Smith, Apr 12 '20 at 08:53

$d = dir(".");

echo "<ul>";

while (false !== ($entry = $d->read()))
{
    if (is_dir($entry) && ($entry != '.') && ($entry != '..'))
        echo "<li><a href='{$entry}'>{$entry}</a></li>";
}

echo "</ul>";

$d->close();

Thanks, that outputs only the folders, without the dots! – Unknown Dec 27 '17 at 21:45

You should just be able to wrap your current code with a call to is_dir:

while(false !== ($entry = $d->read())) {
    if (is_dir($entry)) {
        echo "<li><a href='{$entry}'>{$entry}</a></li>";
    }
}

If you want to remove the "dot" directories (. and ..), use the following:

if (is_dir($entry) && !in_array($entry, ['.', '..'])) {
...

Thanks, that worked like a charm! The only problem i got with this solution is that i get these dots beneath the folders, what's that about? – Unknown Dec 27 '17 at 21:31
@Unknown The dots are another "directory", really it's the parent directory of whatever directory you are in. – GrumpyCrouton Dec 27 '17 at 21:33
I see! Is there a way to remove it from the code, or do i have to use css to remove it? – Unknown Dec 27 '17 at 21:34
Btw, i LOVE this platform. So freaking fast answers, it's pure magic! – Unknown Dec 27 '17 at 21:35
I've added a way to remove the dots – iainn Dec 27 '17 at 21:36

Just check if the $entry is a directory:

$d = dir(".");
echo "<ul>";
while(false !== ($entry = $d->read())) {
if(is_dir($entry))
    echo "<li><a href='{$entry}'>{$entry}</a></li>";
}
echo "</ul>";
$d->close();

OBS! It was this code that worked out of the box with the dots! – Unknown Dec 27 '17 at 21:40
