Use glob
:
if (count(glob("path/*")) === 0 ) { // empty
A nice thing about glob
is that it doesn't return .
and ..
directories.
سؤال
I got a root directory with 100s of dynamically generated folders. As time goes some of these folders will need to be extirpated from system on the condition that this(ese) directories(s) must be empty. What would be the best shortest, easiest and/or most effective way to achieve that?

You can count the items contained in the folder. The first two items are .
and ..
, so just check the items count.
$files_in_directory = scandir('path/to');
$items_count = count($files_in_directory);
if ($items_count <= 2)
{
$empty = true;
}
else {
$empty = false;
}
