I have a php script that uploads a file to the server. Currently only jpg images are allowed. How can I allow more file types to be uploaded such as mp3's, WAV, and GIF?

Code Below:

PHP

<?php
//Сheck that we have a file
if((!empty($_FILES["uploaded_file"])) && ($_FILES['uploaded_file']['error'] == 0)) {
  //Check if the file is JPEG image and it's size is less than 350Kb
  $filename = basename($_FILES['uploaded_file']['name']);
  $ext = substr($filename, strrpos($filename, '.') + 1);
  if (($ext == "jpg") && ($_FILES["uploaded_file"]["type"] == "image/jpeg") &&
    ($_FILES["uploaded_file"]["size"] < 35000000)) {
    //Determine the path to which we want to save this file
      $newname = dirname(__FILE__).'/files/'.$filename;
      //Check if the file with the same name is already exists on the server
      if (!file_exists($newname)) {
        //Attempt to move the uploaded file to it's new place
        if ((move_uploaded_file($_FILES['uploaded_file']['tmp_name'],$newname))) {
           echo "It's done! The file has been saved as: ".$newname;

Any help is greatly appreciated.. Thanks in advance.

I would create a new function to check the type:

function check_file_type($ext, $mime)
{
  $allowed_types = array(
    'jpg' => 'image/jpeg',
    // add other types here
  );
  $ext = strtolower($ext);
  return (array_key_exists($ext, $allowed_types) && $allowed_types[$ext] == $mime);
}

then replace the line:

if (($ext == "jpg") && ($_FILES["uploaded_file"]["type"] == "image/jpeg") &&

with

if (check_file_type($ext, $_FILES["uploaded_file"]["type"]) &&
