is_writable($dir) not working

Question

when I was working with thix thix ix all fine it ix showing all the subfolder and than subfolders of the subfolders

<?php

function listFolderFiles($dir){
    $Folders = scandir($dir);
    echo '<ol>';
    foreach($folders as $subFolders){
        if($subFolders != '.' && $subFolders != '..'){
             echo '<li>'.$subFolders;
             if(is_dir($dir.'/'.$subFolder)) listFolderFiles($dir.'/'.$subFolders);
             echo '</li>';
         }
    }

    echo '</ol>';
}

listFolderFiles('/home/');

?>

but when i changed the code a little bit to check whether any folder is writable than it gave me nothing neither an error nor shown the results.. at the line

if($subFolders != '.' && $subFolders != '..'){
                if(is_writable($subFolders)){
        echo '<li>'.$subFolders.' is witeable :) ';

"i was working with thix thix ix all fine it ix showing", what do you mean ? — mickro, Aug 19 '13 at 22:17

You're close, but missing the full file name. Need the $dir.'/'. part (the parent path):

if(is_writable($dir.'/'.$subFolders)){

are you sure the file is writable to the user owning the web server software? because the code above should in fact be testing whether the file/folder is writable... – Patrick Moore Aug 19 '13 at 22:31
okay i tried ($dir.'/'.$folder.'/'.$subFolders) but not working – Rummy Khan Aug 19 '13 at 22:37
the `.$folder.'/'` part should not be there; there's no reference to a `$folder` variable anywhere in your code. – Patrick Moore Aug 19 '13 at 23:05
