$dir = "upload2/";     if (is_dir($dir)){        if ($dh = opendir($dir)){        while (($file = readdir($dh))!= false){            $filePath = $dir.$file;            echo "";        }        closedir($dh);        }    }

Final form:

$dir = "upload2/"; if (is_dir($dir)){    if ($dh = opendir($dir)){    while (($file = readdir($dh))!= false){        if ($file != "." && $file != "..") {            $filePath = $dir.$file;            echo "";        }    }    closedir($dh);    }}

． Represents the current directory

You can determine whether the directory is in front of the output.
