Doing

file_get_contents($_FILES['uploadedfile']['tmp_name']); 

is valid however you should also check to make sure that the file was uploaded through a form and that no errors occurred during upload:

if ($_FILES['uploadedfile']['error'] == UPLOAD_ERR_OK               //checks for errors
      && is_uploaded_file($_FILES['uploadedfile']['tmp_name'])) { //checks that file is uploaded
  echo file_get_contents($_FILES['uploadedfile']['tmp_name']); 
}
