PHP opendir() to list folders only

Question

I would like to use opendir() to list only the folders in a particular folder (i.e. /www/site/). I would like to exclude files from the list as well at the '.' and '..' folders that appear on a linux folder listing. How would I go about doing this?

Answer 1

foreach(glob('directory/*', GLOB_ONLYDIR) as $dir) {
    $dir = str_replace('directory/', '', $dir);
    echo $dir;
}

You can use simply glob with GLOB_ONLYDIR and then filter resulted directories

Answer 2

Check out the PHP docs for readdir(). It includes an example for exactly this.

For completeness:

<?php
if ($handle = opendir('.')) {
    $blacklist = array('.', '..', 'somedir', 'somefile.php');
    while (false !== ($file = readdir($handle))) {
        if (!in_array($file, $blacklist)) {
            echo "$file\n";
        }
    }
    closedir($handle);
}
?>

Simply change opendir('.') to your directory, i.e. opendir('/www/sites/'), and update $blacklist to include the names of files or directory you do not wish to output.
