Answer 1

originally from php.net:
<?php
$dir = '/uploads/';
if ($handle = opendir($dir)) {
while (false !== ($file = readdir($handle))) {
if ($file != "." && $file != "..") { // strip the current and previous directory items
unlink($dir . $file); // you can add some filters here, aswell, to filter datatypes, file, prefixes, suffixes, etc
}
}
closedir($handle);
}
?>

Answer 2

I found this at php.net:
"The shortest recursive delete possible"
function rrmdir($path) {
return is_file($path)?
#unlink($path):
array_map('rrmdir',glob($path.'/*'))==#rmdir($path)
;
}

You could do it like this:
function delete_files($dirname) {
if (is_dir($dirname))
$dir_handle = opendir($dirname);
if (!$dir_handle)
return false;
while($file = readdir($dir_handle)) {
if ($file != "." && $file != "..") {
if (!is_dir($dirname."/".$file))
unlink($dirname."/".$file);
}
}
closedir($dir_handle);
return true;
}

You need to use a recursive function. A comment from the rmdir page have written a function on how to do it, see http://www.php.net/manual/en/function.rmdir.php#98622. This code will delete the folder and everything in it.
<?php
function rrmdir($dir) {
if (is_dir($dir)) {
$objects = scandir($dir);
foreach ($objects as $object) {
if ($object != "." && $object != "..") {
if (filetype($dir."/".$object) == "dir") rrmdir($dir."/".$object); else unlink($dir."/".$object);
}
}
reset($objects);
rmdir($dir);
}
}
?>
