Unfortunately, the function posted by p dot marzec at bold-sg dot pl does not work.
The corrected version is:
// returns true if folder is empty or not existing
// false if folde is full
function is_empty_folder($dir) {
if (is_dir($dir)) {
$dl=opendir($dir);
if ($dl) {
while($name = readdir($dl)) {
if (!is_dir("$dir/$name")) { //<--- corrected here
return false;
break;
}
}
closedir($dl);
}
return true;
} else return true;
}
