There seems to be a lot of good documentation

for Linux users compiling PHP with DB2 support,

but decent Windows notes are minimal.



You do not need to install full DB2 clients to get DB2

working with DB2, all you need is the IBM Data

Server Driver for ODBC, CLI, and .NET which is only

16.1 meg.



You can download the driver from here:



Direct Link:

ftp://ftp.software.ibm.com/ps/products/db2/fixes2/englsh-us/

db2_v95/dsdriver/fp2/v9.5fp2_nt32_dsdriver_EN.exe



Home Page:

http://www-01.ibm.com/support/docview.wss?rs=71&uid=swg21287889



This includes both the drivers required and the PHP

dll php_ibm_db2_5.2.2.dll



Once installed the drivers do not setup the correct

path environmental variable,

so add the following to your path:



C:\Program Files\IBM\IBM DATA SERVER DRIVER\bin



Once thats done all should work! No massive

400meg client downloads required.



Whats even better about these drivers is that you

dont need to install them,

you can simply copy the bin directory to any server,

add it to your path and it will just work. 

This is great for anyone developing PHP-GTK applications,

I copy the bin directory into my php-gkt2 directory

and execute using the following batch script:



path = %PATH%;.\IBM DATA SERVER DRIVER\bin

php-win.exe %*



This lets me role out lightweight DB2 client desktop

apps that dont have to be installed,

can just be coppied from PC to PC or ran over a

network or from USB stick.



As your only installing the client drivers you wont be

able to catalog databases,

so always use the full connection string. Here is a

quick bit of code to get you started:



$database = 'databasename';

$user = 'user';

$password = 'password';

$hostname = '127.0.0.1';

$port = 50000;



$conn_string = "DRIVER={IBM DB2 ODBC DRIVER};DATABASE=$database;" .

  "HOSTNAME=$hostname;PORT=$port;".

  "PROTOCOL=TCPIP;UID=$user;PWD=$password;";

$conn = db2_connect($conn_string, '', '');



$query = 'SELECT * FROM TABLE';

$res = db2_prepare($conn, $query);

db2_execute($res);



while ($row = db2_fetch_array($res)) {

  print_r($row);

}

Spent a lot of time trying to get this to work on a 64bit box.  You'll need to make sure you set your db2 client to 64 bit mode!  If you didn't set your instance to 64bit, you can run ./db2iupdt -w64 db2instance as root to set it.  Hope this helps someone!

The DB/2 Run-Time-Client can be found here:

http://www-1.ibm.com/support/docview.wss?rs=71&uid=swg21255394

Select the 'Runtime Client Installable for Windows' further down the page and download it. 

Clients for other platform (incl. 64-Bit Windows) are also available from that page.

If you wish to connect to an iSeries Server, such as an AS/400, there are two options. Installing DB2 Express-C v9.5 and purchasing DB2 Connect Personal Edition for about $500 or getting System I Access for Linux, which is a free download. Please note the server requirements for each of these. For example, we originally went with DB2 Express-C and decided upon Ubuntu 7.10, but learned about System I Access, from an IBM rep, which requires redhat package manager, after the entire server was up and running.
