tr doesn't behave in the way you expect. It translitterates characters,
rather than substituting strings. You should be using sed instead:

	for i in *.php3; do mv "$i" `echo "$i" | sed 's/php3$/php/'`; done

Note that you don't need to use ls to get the list of files. The shell's
globbing will do that for you. I've also quoted "$i" where it's referenced,
which ensures it'll still work if you have whitespace in your filenames.
