How do I open a download hint?

Question

I use this to put contents in a file

file_put_contents('abc.txt', $text); 

I need to open a popup for the user to save / load the file as I would do

Answer 1

This will give the user a download request:

<?php                                                                
header('Content-type: text/plain');                             

// What file will be named after downloading                                  
header('Content-Disposition: attachment; filename="abc.txt"');

// File to download                                
readfile('abc.txt');                                            
?>  

Answer 2

The manual fpassthru()provides a complete example.

Answer 3

Use the Content-Disposition header:

header('Content-Disposition: attachment; filename="abc.txt"');
readfile('abc.txt');

Be sure to send the appropriate Content-Type header.

Answer 4

You must pass the correct headers:

header("Content-disposition: Atachment");
