PHP upload files and give a custom name

Question

I am using this function to upload my files:

if ((($_FILES["Artwork"]["type"] == "image/gif")
|| ($_FILES["Artwork"]["type"] == "image/jpeg")
|| ($_FILES["Artwork"]["type"] == "image/jpg")
|| ($_FILES["Artwork"]["type"] == "image/pjpeg"))
&& ($_FILES["Artwork"]["size"] < 20000000))
  {
  if ($_FILES["Artwork"]["error"] > 0)
    {
    //echo "Return Code: " . $_FILES["Artwork"]["error"] . "<br />";
    }else{
      $imageName = $_FILES['Artwork']['name'];
      move_uploaded_file($_FILES["Artwork"]["tmp_name"],
      $path_image . $imageName);
      }
    }else{
    //echo "invalid file";
    }

How do I change $imageName = $_FILES['Artwork']['name']; with a custom name, but mantaining the file extension in the name, so for example: myCustomName.jpg?

Thanks!

Don't use the ['type'] field. That's user-provided data and is trivial to forge. use something server-side, such as FileInfo, to get a mime-type. Still not 100%, but much better than the 0% reliability of the ['type'] field. — Marc B

The only line you need modified in your code is:

$imageName = 'CustomName.' . pathinfo($_FILES['Artwork']['name'],PATHINFO_EXTENSION);

Where 'CustomName.' is the new name you want for the image. pathinfo if the PHP function to handle the operations with paths and files names.

You whole code would be:

if ((($_FILES["Artwork"]["type"] == "image/gif")
|| ($_FILES["Artwork"]["type"] == "image/jpeg")
|| ($_FILES["Artwork"]["type"] == "image/jpg")
|| ($_FILES["Artwork"]["type"] == "image/pjpeg"))
&& ($_FILES["Artwork"]["size"] < 20000000))
  {
  if ($_FILES["Artwork"]["error"] > 0)
    {
    //echo "Return Code: " . $_FILES["Artwork"]["error"] . "<br />";
    }else{
      $imageName = 'CustomName.' . pathinfo($_FILES['Artwork']['name'],PATHINFO_EXTENSION);
      move_uploaded_file($_FILES["Artwork"]["tmp_name"],
      $path_image . $imageName);
      }
    }else{
    //echo "invalid file";
    }

$ext = last(explode('.', $_FILES['Artwork']['name']));
$custom_name = 'something';
$imageName = $custom_name.'.'.$ext;

I think you're making it too complicated. It's as simple as splitting the filename by the dot and using the last element:

$parts = explode('.', $_FILES['Artwork']['name']);
$newname = "myCustomName" . (size($parts) > 1 ? '.' . last($parts) : '')
