problem enabling postgres in php

hello,


I am working with Postgresql 8.1.3, Apache 2.0.58 and PHP 5.1.4. on windows 2k.


My phpinfo is working fine. But I am not able to enable postgres
support. According to phpinfo the configuration file (php.ini) path is
"C:\WINNT".  All my extensions are in the  "C:\php\ext"  dir. I
modified the php.ini file situated in the C:\WINNT dir as follows : 


extension_dir = "C:\php\ext  and also removed the ';' (semicolon)
infront of the extension=php_pgsql.dll  with all the other extension
being blocked by semicolon. Then I restarted the comp but it is not
reflecting the changes in the phpinfo. 


Under the "php configuration core" phpinfo is showing the extension_dir
as C:\php5 and include_path as ".;C:\php5\pear". But i dont have any
directory named php5. So, i created a directory named php5 in C:\ and
copied all the extension dlls into it and made a folder named pear in
it and copied the php.ini file in it. But it still didnt reflect any
changes. 


I doubt that it is not reading the php,ini file from the "C:\WINNT"
directory. To check that I tried changing the color code of 
"highlight.string" from DD0000 to FF9900. I again restarted the comp
but still it didnt reflect this change too. So, i think that it is
using some other php.ini file. So, i searched for the php.ini file and
i found it in the following locations : 


C:\WINNT\

C:\php5\


So, i made the same changes everywhere including the "php.ini-dist" and
"php.ini-recommended" files found in C:\php dir. But still the problem
persisted. Then I removed the php.ini file from the "C:\WINNT" dir but
the phpinfo still worked even without it being present in the dir. 


I also tried reinstalling php several times but that also didnt help.
But what I found strange was that i was not able to remove the
"php5ts.dll"  from the C:\WINNT dir and "php5apache2.dll" from the
C:\php dir. Everytime it gave an error that these files are in use. I
dont have any information about these files. 


Do i have to modify the "System Path variable" ?? I also tried
modifying that too by adding C:\php and C:\php5 in it. I also added one
more system variable PHPRC with the value C:\WINNT. 


But still i am not able to enable the postgres with php. I think there
is no compatibility issues as google search gives some phpinfo links
that works with the same version of php and postgres. When i try to
connect to the database it gives the error "Call to undefined function
pg_connect()" which i think is obvious as phpinfo is not showing
postgres in it. 


It would be a great help if you could figure out the error and can help
me enabling the postgres in php. I have been trying for the past 3 days
to enable it. 


Thanks a lot for spending your valuable time.
