List all folders in directory (PHP) [duplicate]

问题

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();

回答1:

$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();

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, ['.', '..'])) {
...

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();
