Question

Can´t connect to MSSQL from PHP/Apache running on Windows

Asked by: aluna

Hello all,

I've successfully setup AppServ on Windows 7 RC, enabled php_mssql extension, updated ntwdblib.dll, and wrote code to connect to an mssql database. If I run my code in a command prompt using php.exe, I'm able to connect to db and get results as seen on attached cmd-php.jpg image (the php.ini file loaded is on Appserv/php5 folder). But when I run the code from inside a browser, php_mssql extension is not loaded and I can't connect to the sql server as shown on attached browser.jpg image (the php.ini file loaded is on Windows folder). Both php.ini files are identically.

What should I try to get the code to work from inside the browser?

Thank you
Regards
Alex

As you only have the one .ini file, you don't have a "--with-config-file-scan-dir=c:\xxxxxxx" can you have a look to see what extensions are loaded in the C:\Windows\php.ini

You should see lines similar to the following, make sure the mysql and odbc entries are uncommented:

; comment out next line to disable mysql extension in php
extension=mysql.so

; comment out next line to disable mysqli extension in php
extension=mysqli.so

; comment out next line to disable odbc extension in php
extension=odbc.so

Arborer,

This is run on Windows, so extensions are .dll and not .so as in Linux. Also, I´m trying to connect to MS SQL Server and not MySQL, so the extension that need to be loaded is php_mssql.dll and not php_mysql.dll nor php_mysqli.dll.

I have TWO IDENTICAL php.ini files, one in c:\appserv\php5 and other in c:\windows. Both have enabled the php_mssql.dll extension.

When I run the testdb.php file from command prompt using php.exe, the php.ini in c:\appserv\php5 is loaded and mssql.dll´s are loaded also. But if I run testdb.php from inside a browser, the php.ini into c:\windows is used instead, and mssql.dll´s are not loaded.

I think the problem could be the link between PHP and Apache.

Any other suggestion, everyone?

Thanks

Where (which directory) is the php_mssql.dll  located in?

Does it match the extension_dir value in the php.ini e.g.

extension_dir="c:\xxxx\yyyyy\ext"

If not either alter the C:\Windows\php.ini    or copy the DLL's to the directory specified in the file.

 

by: alunaPosted on 2009-09-06 at 07:12:03ID: 25269992

Yes, the php_mssql.dll is located in the extension dir specified on both php.ini files. In fact, the code works when called directly thru php.exe, that's why I think I've missed something that prevents the code to works when called thru Apache.

Thanx

Well, I've changed PHPIniDir in Apache configuration file to force it to use same php.ini as when running php.exe, that is, the php.ini located at c:\appserv\php5, so now I have onlye one php.ini file.

I've been looking at Apache logs and found errors when loading php_mssql.dll:

[Sun Sep 06 20:55:36 2009] [notice] Apache/2.2.8 (Win32) PHP/5.2.6 configured -- resuming normal operations

[Sun Sep 06 20:55:37 2009] [notice] Child 1608: Starting thread to listen on port 8080.

I don't know why Apache can't make PHP to load those libraries as they are in proper place and can be accessed (tried opening dll file contents from withing a web page and it showed up), also dlls for mysql are loaded and working properly.

Now this question turns into: Why Apache can't make PHP to load php_mssql.dll?

Any comment?
Thank you

SOLVED!
Finally I solved this mystery.

The solution was set Apache service to start with administrator account instead of Local System account (this one was assigned upon AppServ installation).

Now php_mssql.dll gets loaded correctly and I can connect to SQL Server 2005 database.
