jchastain Posted February 19, 2007 Share Posted February 19, 2007 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?

wildteen88 Posted February 19, 2007 Share Posted February 19, 2007 Just install PHP5. PHP is backwards compatible with PHP4. Link to comment https://forums.phpfreaks.com/topic/39097-php-4-php-5-on-windows-2k3/#findComment-188808 Share on other sites More sharing options...
jchastain Posted February 19, 2007 Author Share Posted February 19, 2007 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. Link to comment https://forums.phpfreaks.com/topic/39097-php-4-php-5-on-windows-2k3/#findComment-188870 Share on other sites More sharing options...
wildteen88 Posted February 19, 2007 Share Posted February 19, 2007 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.
