Not in most cases. As it has been already said, .php files are interpreted
and run, not read, if the webserver configuration is right.

A way to circumvent this is to make use of some unsecure script that is able
to read files from the server and output it to the client with no or little
checks, something like:
www.myurl.com/download.php?file=../../mypage.php
www.myurl.com/download.php?file=../../../etc/passwd
