Question

What’s the proper syntax for this?

header('Content-Disposition: attachment; filename="{$_SESSION['name']} . '.txt');

This file works, though only properly when “view source” (HTML not formatted but contains correct line breaks).

<?php
header("Content-type: text/html");
session_start();
    if(file_exists("chat") && filesize("chat") > 0){
        $handle = fopen("chat", "r");
        $contents = fread($handle, filesize("chat"));
        fclose($handle);
        ob_start();
$download = strip_tags($contents, '<br>');
$processed = preg_replace('#<br\s*/?>#i', "\n", $download);
echo $processed;
$var = ob_get_clean();
echo $var;
    }
?>

The $_SESSION['name'] variable is something like guest_158512 and if you view the source of the page I’m trying to save, it has all the line breaks. How do I save the current page as guest_158512.txt with the proper syntax?

Your problem here is that you’ve tried to use single quotes. Single quotes do not interpolate variables in PHP.

You have also failed to properly terminate the string, probably due to putting more single quotes inside it. Try:

header('Content-Disposition: attachment; filename="'.$_SESSION['name'].'.txt"');

Kolink also points out that you should use Content-Type: text/plain to serve plain-text non-HTML files.
