Allow me to code that for you....
<?php
$root = __DIR__;
function is_in_dir($file, $directory, $recursive = true, $limit = 1000) {
$directory = realpath($directory);
$parent = realpath($file);
$i = 0;
while ($parent) {
if ($directory == $parent) return true;
if ($parent == dirname($parent) || !$recursive) break;
$parent = dirname($parent);
}
return false;
}
$path = null;
if (isset($_GET['file'])) {
$path = $_GET['file'];
if (!is_in_dir($_GET['file'], $root)) {
$path = null;
} else {
$path = '/'.$path;
}
}
if (is_file($root.$path)) {
readfile($root.$path);
return;
}
if ($path) echo '..<br />';
foreach (glob($root.$path.'/*') as $file) {
$file = realpath($file);
$link = substr($file, strlen($root) + 1);
echo ''.basename($file).'<br />';
}
