PHP read from uploaded text file?

php file upload

Dan · Feb 4, 2010 · Viewed 90.6k times · Source

If I upload a text file via a form, is it possible to output its contents directly from the $_FILES variable rather than saving it onto the server first? I know this is a security risk, but it will only be run on a local machine.

Any advice appreciated.

Thanks.

Answer

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']); 
}
