recursive function

[trefrog]

I'm trying to make a script that goes thru all the subfolders within a directory. Later I'll add a part to insert the folder names into a database. The problem is my function won't go any deeper than 2 levels and I haven't been able to figure it out. Can anyone see the problem with this?

function subfolders($folderIn = '', $levelIn = 0) {
    $folderName = $folderIn;
    $folderIn .= ($folderIn!='') ? '/' : '';
    $levelOut = $levelIn+1;
    $tmp = glob($folderIn.'*', GLOB_ONLYDIR);
    foreach($tmp as $key=>$value) {
        $dir[] = end(explode('/', $value));
        $tab = '    ';
        $str = '';
        for($i=0; $i<$levelIn; $i++) { $str .= $tab; }
        echo $str.$dir[$key]."\n";
        subfolders($dir[$key], $levelOut);
    }
}

echo '<pre>'."\n";
subfolders();
echo '</pre>'."\n";

nevermind... I wasn't giving glob() the full path.

subfolders($folderIn.$dir[$key], $levelOut);
