Answer 1

$_FILES['Filedata']['name'] has your filename, you can replace that but first you need to get the file's extension if it's not the same all the time.

$p = pathinfo($_FILES['Filedata']['name']);
$newName = time() . "." . $p['extension'];
$targetFile =  str_replace('//','/',$targetPath) . $newName;
