php 5.3 in apache in windows

[quote author="Chad Fulton" date="1246576407"]You should also note that there are issues with PHP 5.3 and CodeIgniter. The URI filter will fail by default (http://codeigniter.com/bug_tracker/bug/7126/).[/quote]
Oh! Is it possible to install both version of php 5.2 and 5.3 on same server(but different virtual hosts)?

You are better off installing it manually using the zip file. And then
LoadModule php5_module "C:/php/php5apache2_2.dll"
AddType application/x-httpd-php .php

in the httpd.conf to handle the php page requests through apache.
“C:/php/php5apache2_2.dll” should be replaced with full path to the dll file on your machine.

Thanks! that worked perfectly. But just one more problem. I have several virtual hosts i.e.
server1.localhost
server2.localhost
system.localhost
localhost

php only working on http://localhost not on other virtual hosts. How to enable php 5.3 on other vhosts too.
