Create a text file for download on-the-fly

Question

Update  1  What has been posted below is spot on for getting it to output the file  What it is doing though is outputting the string data followed by the rest of the forms HTML  Is there any way to stop what is put into the file and what is just displayed to the browser   Update  2  Just added exit   and all works fine  Thanks   EOU  Hi   I ve been looking around and seen a few things similar but not quite fully got the grasp on what I need to do to achieve the task fully   At the moment I have a form that a user supplies some details  On submit it is posted back to itself and the POST variables processed  I have a premade HTML web template for the information to be placed into which works fine and dandy just doing a str replace   What I am trying to do now is export that as a download to the user in a plain text document  So the end result being the user clicks submit on the form and they then have a download popup open with the modified webpage as a  txt file   As far as I understand I need to do something using HTTPs headers functionality  What exactly though to achieve what I want I m not sure  I only want the file to be available once  but I assume it has to be stored somewhere initally for the user to download which will then need cleaing up after manually   Any help or points would be great  Thanks

No need to store it anywhere  Just output the content with the appropriate content type    lt  php     header  Content-type  text plain      gt Hello  world    Add content-disposition if you wish to trigger a download prompt   header  Content-Disposition  attachment  filename  default-filename txt

Check out this SO question s accepted solution  Substitute your own filename for basename  File  and change filesize  File  to strlen  your string    You may want to use mb strlen just in case the string contains multibyte characters
