I have seen functions to list all file in a directory but how can I list all the files in sub-directories too, so it returns an array like?

$files = files("foldername");

So $files is something similar to

array("file.jpg", "blah.word", "name.fileext")

I think you're looking for php's glob function. You can call glob(**) to get a recursive file listing.

EDIT: I realized that my glob doesn't work reliably on all systems so I submit this much prettier version of the accepted answer.

function rglob($pattern='*', $flags = 0, $path='')
{
    $paths=glob($path.'*', GLOB_MARK|GLOB_ONLYDIR|GLOB_NOSORT);
    $files=glob($path.$pattern, $flags);
    foreach ($paths as $path) { $files=array_merge($files,rglob($pattern, $flags, $path)); }
    return $files;
}

function files($path,&$files = array())
{
    $dir = opendir($path."/.");
    while($item = readdir($dir))
        if(is_file($sub = $path."/".$item))
            $files[] = $item;else
            if($item != "." and $item != "..")
                files($sub,$files); 
    return($files);
}
print_r(files($_SERVER['DOCUMENT_ROOT']));

foreach (new RecursiveIteratorIterator(new RecursiveDirectoryIterator('.')) as $filename)
{
    // filter out "." and ".."
    if ($filename->isDir()) continue;

    echo "$filename\n";
}

I needed to implement the reading of a given directory, and relying on the function of Chuck Vose, I created this page to read the directories relying on JQuery:

<?php

/**
 * Recovers folder structure and files of a certain path
 * 
 * @param string $path Folder where files are located
 * @param string $pattern Filter by extension
 * @param string $flags Flags to be passed to the glob
 * @return array Folder structure
 */
function getFolderTree($path)
{
    //Recovers files and directories
    $paths = glob($path . "*", GLOB_MARK | GLOB_ONLYDIR | GLOB_NOSORT);
    $files = glob($path . "*");

    //Traverses the directories found
    foreach ($paths as $key => $path)
    {
        //Create directory if exists
        $directory = explode("\\", $path);
        unset($directory[count($directory) - 1]);
        $directories[end($directory)] = getFolderTree($path);

        //Verify if exists files
        foreach ($files as $file)
        {
            if (strpos(substr($file, 2), ".") !== false)
                $directories[] = substr($file, (strrpos($file, "\\") + 1));
        }
    }

    //Return the directories
    if (isset($directories))
    {
        return $directories;
    }
    //Returns the last level of folder
    else
    {
        $files2return = Array();
        foreach ($files as $key => $file)
            $files2return[] = substr($file, (strrpos($file, "\\") + 1));
        return $files2return;
    }
}

/**
 * Creates the HTML for the tree
 * 
 * @param array $directory Array containing the folder structure
 * @return string HTML
 */
function createTree($directory)
{
    $html = "<ul>";
    foreach($directory as $keyDirectory => $eachDirectory)
    {
        if(is_array($eachDirectory))
        {
            $html .= "<li class='closed'><span class='folder'>" . $keyDirectory . "</span>";
            $html .= createTree($eachDirectory);
            $html .=  "</li>";
        }
        else
        {
            $html .= "<li><span class='file'>" . $eachDirectory . "</span></li>";
        }
    }
    $html .= "</ul>";

    return $html;
}

//Create output
$directory = getFolderTree('..\videos');
$htmlTree = createTree($directory["videos"]);
?>

            </ul>
        </div>
    </body>
</html>

The structure used in the tree with JQuery, the site was taken: http://jquery.bassistance.de/treeview/demo/

I hope it is useful!

So you're looking for a recursive directory listing?

function directoryToArray($directory, $recursive) {
    $array_items = array();
    if ($handle = opendir($directory)) {
        while (false !== ($file = readdir($handle))) {
            if ($file != "." && $file != "..") {
                if (is_dir($directory. "/" . $file)) {
                    if($recursive) {
                        $array_items = array_merge($array_items, directoryToArray($directory. "/" . $file, $recursive));
                    }
                    $file = $directory . "/" . $file;
                    $array_items[] = preg_replace("/\/\//si", "/", $file);
                } else {
                    $file = $directory . "/" . $file;
                    $array_items[] = preg_replace("/\/\//si", "/", $file);
                }
            }
        }
        closedir($handle);
    }
    return $array_items;
}
