i tried to create a download script (download.php). The content of the script goes like:

<?php
$path=&quot;./myfiles&quot;;
$filename=&quot;computer.jpg&quot;

header(&quot;Content-Disposition: attachment; filename=$filename&quot;)
header(&quot;Content-Transfer-Encoding: binary&quot;);
header(&quot;Content-Type: applicatin/octet-stream&quot;);
readfile(&quot;$path/$filename&quot;);
?>

the output:

Warning: Cannot modify header information - headers already sent by (output started at /usr/local/apache2/htdocs/mypage/download.php:2) in /usr/local/apache2/htdocs/mypage/download.php

These messages points at all the lines beginning the &quot;header&quot;.

What does this error means? How do i go about it?

thanks,

Note the missing semicolons. //Daniel

oops, sorry... the actual script do have all these semicolons and i dont say any other typo errors.

what else could be the reason for these errors? i'll be looking at some configuration files for both php and apache. meanwhile, hope you could share your ideas.

thanks,

make sure that no output is sent to the browser before u use header.
is there any blank line or blank space before ur php start tag?

daniel, i removed the html tags e.g.,<html>,etc. and with my script starting with <?php tag. the error messages were gone, but it displays the content of the file, i.e, the computer image in the browser. i want it to be copied into my local win98 PC instead. how? any further corrections?

ne4x4, my php4.3.0 is installed together with my apache2.0.40 at my redhat 7.3 server in my LAN.

thanks again,
