PHP 4 + PHP 5 on Windows 2K3?

[jchastain]

I have two different php applications that I am trying to install on a Windows 2003 / IIS 6 server.  One application requires php 4 and one requires php 5.  I have found a couple of sites that talk about running both in parallel, but I am not being able to work.  Is there a set of instructions anywhere that show this is really possible?

 

Thanks

Just install PHP5. PHP is backwards compatible with PHP4.

I am not knowledgeable enough about PHP, but one of the applications is not compatible with some aspect of PHP 5.  It requires PHP 4.x and throws errors otherwise.  Any time I have gone back to the vendor with the errors, they have stated that it must run on PHP 4.

 

I have both PHP 4 and 5 installed as was detailed in one of the articles I found, but the PHP 4 install is trying to use the php.ini file in the PHP 5 folder instead of the one in the PHP 4 folder.

 

Thanks.

You cannot run both versions at the same time. You will have to reconfigure IIS to use php4 instead of php5 by changing IIS's configuration each time and renaming/moving PHP4 and PHP5 configuration as well. Rather tedious task.
