Answer 1

I would not add a date to the file if it already exists. Instead I would just add a number to the end of it. Keep it simple.

$counter = 0;
do {
    // destination path path
    $destination = $path.'/'.$upload_to.'/';

    // get extension
    $file_ext = end(explode('.', $file_name));

    // add file_name without extension
    if (strlen($file_ext))
        $destination .= substr($file_name, 0, strlen($file_name)-strlen($file_ext)-1);

    // add counter
    if ($counter)
        $destination .= '_'.$counter;       

    // add extension
    if (strlen($file_ext))
        $destination .= $file_ext;

    $counter++;
while (file_exists($destination));

// move file
move_uploaded_file($tmp, $destination);
