The following instructions describe the process of installing both PHP 4.x and PHP 5.x in CGI mode on the same server:

1. Unpack PHP 4 distributive to "c:\php4" folder.

2. Unpack PHP 5 distributive to "c:\php5" folder.

3. Set "Read" NTFS permissions for "DNPWebUsers" group (or orther specified on WEB service properties page in DNP) on both "c:\php4" and "c:\php5" folders.

4. Rename "c:\php4\php.ini-recommended" to "c:\php4\php.ini".

5. Open "c:\php4\php.ini" for editing and change the following settings:

cgi.force_redirect = 0
extension_dir = "c:\php4\extensions\"

6. Save "c:\php4\php.ini" and close.

7. Rename "c:\php5\php.ini-recommended" to "c:\php5\php-cgi-fcgi.ini".

8. Open "c:\php5\php-cgi-fcgi.ini" for editing and change the following settings:

short_open_tag = On
cgi.force_redirect = 0
extension_dir = "c:\php5\ext\"

9. Save "c:\php5\php-cgi-fcgi.ini" and close.

10. In IIS manager under "Web Service Extensions" node add two new web extensions:

"PHP 4" with required file "c:\php4\php.exe"

and

"PHP 5" with required file "c:\php5\php-cgi.exe"

11. Set both extensions status to "allowed".

12. If you have previously installed PHP 4 or PHP 5, please, make sure you don't have a) any PHP libraries in "c:\windows\system32", b) php.ini in "c:\windows" and c) paths to PHP folders in PATH system variable.

In IIS 6.0 -> Website Properties -> Home Directory Tab -> Configurations -> mappings

should the php listed in the application extensions be deleted or edited? And if so should this be done under the main web sites folder or just on dotnetpanel?

Also after I followed this how-to. I went into the server admin part of the control panel and I input the php pathways according in the web server configuration.

I logged in as a client into my control panel on one of my websites and then website properties -> extensions and for php drop down menu only none / php4 are shown and not php5!

did I miss something Feordor?

thanks for your help

DNP will do mappings automatically when you enable/disable/switch PHP for the web site.

Yes, make sure you have both PHP 4 and 5 enabled in your hosting plans.

I read your post and you stated that we should remove any php.ini from C:/windows if we did a previous install. However I have a Apache webserver on the same server box running on a different port and some of the scripts on there require the php.ini in C:/windows or it will get a undefined error when calling mysql function.

Can I leave the original php.ini file in c:/windows or would leaving it cause errors in DNP??

Basically I am looking for a work around.

Woof, only the experiment will show which php.ini will be loaded. Btw, I would recommend you to play with FileMon utility from SysInternals (http://www.sysinternals.com/FileAndDiskUtilities.html) and see what files are requested when.

Edit: I saw some guys on the Internet were recompiling original PHP sources to get php.ini from proper location

I'm having some problem install php. I have install by following your instructions, but when I'm trying to run php my server. I get this error message.

Feodor can you help me please!

Check the following:

1. Both PHP folders have "Read" permission enable for "DNPWebUsers". Try to enable "Read" for NETWORK SERVICE and see if it helps.

2. Both PHP Web Extensions are "Allowed" in IIS admin tool.

I would recommend you to install PHP on IIS using the PHP readme. I can assure you step-by-step configuration using a native readme is the most comprehensive guide.

Actually it shouldn't takes from you more than 30-40 minutes to run PHP but please be patient, accurate, consistent and scrupulous and you'll get the result!

PS. Check does the .php extension is correctly mapped on both levels Web Service extensions and website. If the path to the php.exe contains spaces please double-quote it.

A question on the side here, what's the difference between mapping to the php.exe and php isapi module?

I am asking because, under IIS I have allways mapped the extention to php5isapi.dll and not to php.exe, and I have also set the path to the isapi module in DNP IIS service properties and not to the php.exe.

PS: I am currently only running PHP5.
