Alright, David, I'm pleased with how far I've gotten with this so far

$ pwd
/var/www
$ ls
CCE0-705F index.html read_dir1.php read_dir3.php read_dir5.php
date.php music1 read_dir1.php~ read_dir3.php~ read_dir5.php~
date.php~ music1.sh read_dir2.php read_dir4.php test.php
hello.php music1.sh~ read_dir2.php~ read_dir4.php~ Untitled Document
$ cat read_dir4.php
<?php

function getFilesFromDir($dir) {

$files = array();
if ($handle = opendir($dir)) {
while (false !== ($file = readdir($handle))) {
if ($file != "." && $file != "..") {
if(is_dir($dir.'/'.$file)) {
$dir2 = $dir.'/'.$file;
$files[] = getFilesFromDir($dir2);
}
else {
$files[] = $dir.'/'.$file;
}
}
}
closedir($handle);
}

return array_flat($files);
}

function array_flat($array) {

foreach($array as $a) {
if(is_array($a)) {
$tmp = array_merge($tmp, array_flat($a));
}
else {
$tmp[] = $a;
}
}

return $tmp;
}

// Usage
$dir = 'music1';
$foo = getFilesFromDir($dir);

print_r($foo);
?>
$

This is my fourth version of this script, obviously written primarily by
someone with more experience.

The output is tremendous, and the next step is to use a regex to knock
off leading numbers and underscores. I have a simple question.

Given that you have the data in an array that is instantiated like this,
how does one use best php form to use a regex on the whole thing?
