Dear Kaushik,

you can make PHP3 and PHP4 work simultaniously without any problems.
Therefore you have to install a second
webserver, for example Apache 1.3.12 and
compile this with PHP4.
This webserver should act on an other port
than 80 (default HTTP-Port), let's say it should work on port 81.
The document-root can show to the same
directory to which the other Webserver shows.
Then you have a great test environment for
switching between PHP3 and PHP4 with typing
http://localhost/info.php or
http://localhost:81/info.php

We tried this with two Apaches (1.3.9) and (1.3.12) and PHP 3.0.12 directly compiled in the first and PHP 4.0.0 as DSO in the second.
This all on Suse Linux 6.3.
Everything works fine.

Hope this helps!
