Directory tree as an associative array?

[eluser]TheFuzzy0ne[/eluser]
Here's a function that will allow limited recursion.

Code:

# Original PHP code by Chirp Internet: www.chirp.com.au

function getFileList($dir, $recurse=false, $depth=false)
{
    # array to hold return value
    $retval = array();

    # add trailing slash if missing
    if(substr($dir, -1) != "/") $dir .= "/";

    # open pointer to directory and read list of files
    $d = @dir($dir) or die("getFileList: Failed opening directory $dir for reading");
    while(false !== ($entry = $d->read())) {
        # skip hidden files
        if($entry[0] == ".") continue;
        if(is_dir("$dir$entry")) {
            $retval[] = array(
                    "name" => "$dir$entry/",
                    "type" => filetype("$dir$entry"),
                    "size" => 0,
                    "lastmod" => filemtime("$dir$entry")
                );
            if($recurse && is_readable("$dir$entry/")) {
                if($depth === false) {
                    $retval = array_merge($retval, getFileList("$dir$entry/", true));
                } elseif($depth > 0) {
                    $retval = array_merge($retval, getFileList("$dir$entry/", true, $depth-1));
                }
            }
        } elseif(is_readable("$dir$entry")) {
            $retval[] = array(
                    "name" => "$dir$entry",
                    "type" => mime_content_type("$dir$entry"),
                    "size" => filesize("$dir$entry"),
                    "lastmod" => filemtime("$dir$entry")
                );
        }
    }
    $d->close();

    return $retval;
}
