If you want to have a copy of favicon.ico in other directories also besides the document root for statistics about which pages are bookmarked from M$ Internet Exploder 5.5 or for performance reasons, and you have a lot of directories, only some of which must receive a copy of favicon.ico, then use this PHP script to accomplish that as intelligently and easily as possible without risking getting RSI of the tedious job by doing it manually. Secondly, if for some mysterious reason favicon.ico is deleted from all directories on your web site (but you still have a backup copy of course), you can easily redistribute it without having to do the tedious job again.
