Using Php To Force A Download?

My website hosts some small .avi and .mpg video clips, which unfortunately, IE's default configuration decides its best to open in Windows media player, and then "streams" it from the server (I realise this is called HTTP Progressive downloading).. Is there a way for the server, either via .htaccess or php code (perhaps header setting?) to control how the file it to be handled? I'd like to be able to force a click on the link to prompt for download..

Any ideas? Thanks in advance!

Yes php is awesome but it is sooo slow.

A much easier, faster, and more efficient way would be to add the following lines to your .htaccess file




Then in your HTML you could just link directly to the file..




And then you will get a pop-up box asking whether you want to save the file or open it.
