Need some help in PHP...

[admin]

OK what I am trying to do is create an avatar hack for my phpBB much like the ones for a UBB. What I need to know is how would I create a list of the files in a directory using PHP so that I don't have to manualy enter the url to each avatar. Anyone know how to do this or have a clue where to start?Something like this?

<?php
$basedir = "/usr/local/www/htmlwiz/phpMisc/"; // Base directory

function listall($dir)
{
// Initialize temporary arrays for sorting
$dir_files = $dir_subdirs = array();

// Print current directory
print("<ul>");
print("<li><b>$dir</b>\n");

// Change to directory
chdir($dir);

// Open directory;
$handle = @opendir($dir) or die("Directory \"$dir\"not found.");

// Loop through all directory entries, construct
// two temporary arrays containing files and sub directories
while($entry = readdir($handle))
{
if(is_dir($entry) && $entry != ".." && $entry != ".")
{
$dir_subdirs[] = $entry;
}
elseif($entry != ".." && $entry != ".")
{
$dir_files[] = $entry;
}
}

// Sort files and sub directories
sort($dir_files);
sort($dir_subdirs);

// Print all files in the curent directory
for($i=0; $i<count($dir_files); $i++)
{
print("<li>$dir_files[$i]\n");
}

// Traverse sub directories
for($i=0; $i<count($dir_subdirs); $i++)
{
listall("$dir$dir_subdirs[$i]/");
}
print("</ul>");

// Close directory
closedir($handle);
}

listall($basedir);
?>
