phpfile


Solution 1:[1]

You could use pathinfo():

$path_parts = pathinfo($_FILES["file"]["name"]);
$extension = $path_parts['extension'];

Solution 2:[2]

Yes you can use $_FILES['file']['name'] to get the original name of the uploaded file. Just keep in mind that the extension may not always represent the real contents of the file.

Solution 3:[3]

Yes, assuming it's accurately named. It will retain its original name and extension.
