<?php
public static function isEmptyDir($dir){
return (($files = @scandir($dir)) && count($files) <= 2);
}
?>
This function is nice, but wrong. If scandir($dir) fails, function will return false, meaning that
directory ist not empty. Use negation logic:
<?php
public static function isEmptyDir($dir){
return (!(($f = @scandir($e)) && count($f) > 2));
}
?>
