$ar=scandir($dir);
$box=$_POST['box']; // Receive the file list from form
// Looping through the list of selected files ///
while (list ($key,$val) = #each ($box)) {
$path=$dir ."/".$val;
if(unlink($path)) echo "Deleted file ";
echo "$val,";
}
echo "<hr>";
/// displaying the file names with checkbox and form ////
echo "<form method=post name='f1' action=''>";
while (list ($key, $val) = each ($ar)) {
if(strlen($val)>3){
echo "<input class=roundedOne id=roundedOne type=checkbox name=box[] value='$val'>$val<br>";
}

Answer 1

This function will delete subfolders and its files:
function removeDir($dir) {
if (is_dir($dir)) {
$objects = scandir($dir);
foreach ($objects as $object) {
if ($object !== '.' && $object !== '..') {
if (filetype($dir.'/'.$object) === "dir") {
removeDir($dir . '/' . $object);
}
else {
unlink($dir.'/'.$object);
}
}
}
reset($objects);
unlink($dir);
}
}
You can use it by executing removeDir($dir);
