PHP 4 + PHP 5 on RH 9

Running both flavors; is it possible?

[henry0]

Hello
I am reworking a few scripts for test purposes
My test bed is RH 9 with a PHP 4 flavor
I would like upgrading to 5 but I wish to keep my PHP 4.
How can I run both short of 2 full RH install

thank you

Regards

Henry

Sorry
I forgot it was a question asked earlier on PHP5.0 release thread.
and the answer seems to be NO
any other input?

[Edit]
<<<
it should be possible to dual boot two RH
each running a PHP flavor
however I have never installed two similar RH on the same machine
While I think about it I am not sure that it can be achieved
