This link might help you:

http://www.php.net/manual/en/faq.migration5.php

"You can run PHP4 and PHP5 as Apache2 modules at the same 
time. The trick is to hack the sources a little bit.
Change all occurences of application/x-httpd-php (and MIME 
type for sources) to application/x-httpd-php5 and then add 
that mime type to apache conf."

You could also use php5 to parse php4 code;

"The main change in PHP 5 is to the OOP model as PHP 5 now 
uses the Zend Engine 2.0. The  zend.ze1_compatibility_mode 
directive enables compatability with the Zend Engine 1.0 
(PHP 4)"
