readdir che resituisce solo cartelle

[Roverandom]

Nemmeno questo funzionava, allora ho trovato questo, che va alla grande

function scanDirectories($rootDir) {
    // set filenames invisible if you want
    $invisibleFileNames = array(".", "..", ".htaccess", ".htpasswd");
    // run through content of root directory
    $dirContent = scandir($rootDir);
    $allData = array();
    // file counter gets incremented for a better
    $fileCounter = 0;
    foreach($dirContent as $key => $content) {
        // filter all files not accessible
        $path = $rootDir.'/'.$content;
        if(!in_array($content, $invisibleFileNames)) {

              if(is_dir($path) && is_readable($path)) {
                $dirNameArray = explode('/',$path);
                $allData[$path]['dirPath'] = $path;
                $allData[$path]['dirName'] = end($dirNameArray);
                // recursive callback to open new directory
                $allData[$path]['content'] = scanDirectories($path);
            }
        }
    }
    return $allData;
