Wie zum Hochladen von text -, pdf -, doc, zip-Datei per PHP Datei upload MySQL

Ich nur implementiert, ein Bild-upload auf MySQL über PHP. Aber ich will hochladen, text, pdf, doc, zip-Datei, um MySQL. Das ist mein code. Wie es zu ändern ?

//uploadAction.php

mysql_connect("localhost", "root", "1989") 

or die(mysql_error());

mysql_select_db("uploadfile") or die(mysql_error());


$sql_id = "SELECT (MAX(id)+1) as \"result\" FROM save";

$rs_id = mysql_query($sql_id);

$row_id = mysql_fetch_assoc($rs_id);

$id = $row_id['result'];

if($id == null)

$id = 1;    

$newName = '';  

$file = $_FILES['photo']['name'];

if ((($_FILES["photo"]["type"] == "image/gif")||

($_FILES["photo"]["type"] == "image/jpeg")||

($_FILES["photo"]["type"] == "image/pjpeg"))

&& ($_FILES["photo"]["size"] < 200000))
{

if ($_FILES["photo"]["error"] > 0)

    echo "Return Code: " . $_FILES["photo"]["error"] . "<br />";

  else{  

      $newName = "$id.".basename($_FILES["photo"]["type"]);

      move_uploaded_file($_FILES["photo"]["tmp_name"], "images/" . $newName);

      }

} 

else

  {

  echo "Invalid file";

  }

$queryUser = "INSERT INTO save VALUES(NULL, \"$newName\")";

$insert = mysql_query($queryUser);

if(!$insert){

    echo mysql_error().'Upload Fail';

  }else {

    echo "<script>alert('Upload Sccessful');";

    echo 'window.location="index.php";</script>';
}

Datenbank SQL

CREATE TABLE `save` (

  `id` int(255) NOT NULL auto_increment,

  `photo` varchar(255) character set utf8 collate utf8_unicode_ci NOT NULL,

  PRIMARY KEY  (`id`)

)
