Installing PHP on W2k with IIs 5

graemes

The program installs and runs the phpinfo test ok. As I require informix connectivity I have removed the comment mark in front of the php_ifx.dll in the extensions part of the php.ini file. The moment I do this an error message "Unable to load dynamic library C:\php\extensions/php_ifx.dll not found. The dll is there, the extensions directory in the php.ini file is correct - does the "/" have any significance ?. I have searched the web relating to this and some responses suggest putting the libsasl.dll in the winnt\system32 directory which I've done. I have given user access to the php directories and other associated dll's. There seems to be no definitive answer can somebody help ?

I would think that you have to use the slashes all in the same direction.. forward or backslash works within windows.

graemes

I do have the slashes the correct way for Windows "\" however when the error is reported it inserts a "/" - I have seen ths problem reported before but again no definitive answer

Anon

what does your:

extension_dir = "d:\server\php\extensions"

line look like in your php.ini

Anon

An extract from the php.ini file :

; Directory in which the loadable extensions (modules) reside.
extension_dir = "C:\php4.1.1\extensions"
extension=php_gd.dll
extension=php_db.dll
;extension=php_ifx.dll
extension=php_zlib.dll

The install was to c:\php4.1.1

Anon

if you cut and pasted that.. you have php_ifx.dll as commented out... have you tried using any other functions that require other dlls? like GD?

graemes

its only commented out to make php work , no I haven't tried any other dlls - when you run the php4 easy windows installer (ver 4.0.4) these dll's are uncommented so I retained them in my 4.1.1 file.

FYI

I've just spent an age racking my brains with EXACTLY the same problem.

Eventually I tried uncommenting all the extensions in the ini file, and found that some worked and some did'nt. (I have all the dll's in the c:\php\extensions dirctory).

This confirmed there was nothing wrong with the ini settings.

Then I trawled the install.txt file that comes with the php.zip and found the comments below

ATTENTION! ATTENTION! ATTENTION!
Some extra DLLs are required for some PHP extensions. Please copy the
bundled dlls from the 'dlls/' directory in distribution package to your
windows/system (Win9.x) or winnt/system32 (WinNT, Win2000, XP) directory.
If you already have these DLLs installed on your system,
overwrite them only if something is not working correctly.
Before overwriting them, it is a good idea to backup them or move them to
another folder - just in case something goes wrong.

Download the latest version of the Microsoft Data Access Components (MDAC)
for your platform, especially Microsoft Windows 9x/NT4 users.
MDAC is available at http://www.microsoft.com/data/ .

Also note that some extensions need 3rd party libraries,
e.g. php_oci8.dll needs the Oracle 8 client libraries to be installed
on your system. These are not bundled with PHP distribution.

ATTENTION! ATTENTION! ATTENTION!

It looks tome that the message: Unable to load dynamic library C:\php\extensions/php_ifx.dll not found." is a might misleading and that in actual fact we may need to look into which 3rd party libraries are required....

I think you are correct in your assumption. I moved all the dll's associated with php into the /winnt/system32 directory with no luck. I downloaded a dll tracer which will check dlls for associated dlls and even monitor the running of php.exe. Everything checked out ok - the output from this "dll walker" was excellent. I think in my case because I require Informix connectivity , (which has been loaded on the server and tested ok) I suspect something doesn't like being called from the browser program. I guess what I'm trying to say all the required dll's are present , they all have the appropriate execute permissions but some registry parameters are not being passed across to the Informix connection modules.
What next ?

Success at last...

Downloaded and installed the INFORMIX Client SDK...

http://www.informix.com/evaluate/

(IBM IFMX CLIENT SDK 2.70.TC3-1 for INTEL WINDOWS NT 4.0)

Everything now works as advertised

also check out http://www.prstech.com/src/php/php_info/informix_tech_notes_on_php.html for an excellent guide on basics.

Hope all goes well

Thanks for that Richard - I downloaded the SDK client for Server 2000 installed it, ran the setnet utility, rebooted and yes it worked. Thank you for your assistance, It seems that the Informix connect product has different functionality to the SDK client product.

What the difference is between them I don't know. Thanks again.
