Using Header

[cbossen]

I am trying to figure out how to use the header function. I want to enable users to download files. I keep getting errors when I try to use the function.

Here is my code:

header("Content-type: $type");
header("Content-length: $size");
header("Content-Disposition: attachment; filename=$name");
header("Content-Description: PHP Generated Data");

Here is an example of the errors I am getting:

Warning: Cannot add header information - headers already sent by (output started at /Users/cbossen/Sites/download/download.php:1) in /Users/cbossen/Sites/download/download.php on line 13

Any help would be much appreciated...

You can't send headers once you have started sending anything else to the user. You should check you code for any extra spaces before or after <?php ?> or any echo/print statements that you are sending before you are calling [man]header()[/man]. All [man]header()[/man] does is modify the headers that Apache is going to send back. But once Apache sees that something is ready to be sent to the user it sends the Headers and you can no longer modify them.
