Hi all, I use now php 4.3.0 and have many scripts and won't it uninstall or delete.
But I will now testing some things with the new one version: php 5.

How can I run the both versions of php on the same Apache 2.0 Server on Windows?
Is this posible?

Thanks and regards!
Nikolay

The only way to run 2 php version on 1 server is to use Apache and have 1 PHP compiled as apache module and the other as CGI.

The apache version of PHP will be much faster then a CGI one.

my host is moving us from the apache version to the cgi version may 12.

what do I need to be aware of as far as potential problems??

if the apache version is faster why go to the cgi version??

The CGI version is arguably more secure. As for possible problem, search on Google Smile

If someone is really wanting to run both PHP 4 and PHP 5 on one server, have a look here:

Also, CGI isn't always "much" slower than Module.

If the CGI binary and the HTTP children can all fit into RAM cache, then the hard drive doesn't get hit on every page load.

Once your CGI gets page-faulted to hard drive though, on a busy server, things go bad really fast.

[Or so I understand it...]

I did not read all the articles from the FAQT link, but if none of them discuss the ProxyPass option of running 2 apache servers, but having one of them "front" for the other, so you can get PHP as module on the 2 pools, while keeping a common "face" to the world, then you need to search PHP-General for Rasmus Lerdorf's post about this.

As far as missing features in CGI, the biggie is HTTP Authentication, as I recall. Apache/PHP are unwilling to schlep your HTTP Auth user/pass through the CGI command, as it would be visible to anybody who can run "ps auxwwww" and catch it as it goes by. (This is from memory from years ago, mind you, so I could be "off" a bit...)

There are also some real esoteric functions/features you are unlikely to notice at all missing from CGI -- So esoteric I've forgotten what they are. Again, years old info, so maybe there's more now that gets lost going from Module to CGI.

For the average webhosted shared site, a change from Module to CGI probably won't impact you at all, except possibly the speed issue -- And your webhost is probably fairly confident on that one, or they'd not go this route.
