Connect to DB2-win2k through PHP4-Linux

Hi, I have a windows 2000 Database Server with IBM DB2 V7.2 on it. I have a Web Server with Linux-Apache-PHP 4 on it (but not XWindow or any graphical interface...). On the web server, I want to run a PHP page to connect to the IBM DB2 Database on the win2k server. 1.> Do I need to install DB2 Client / DB2 Administration Client / DB2 Development Client on the Linux server ? I currently only installed DB2 Client. 2.> After compiling PHP with option --with-ibm-db2=/usr/IBMdb2/V7.1 (I know it's V7.2, but my colleague who did the install believed it was 7.1), can use the PHP command odbc_connect ? When I tried I received the error: "Fatal error: Call to undefined function: odbc_connect()"... 3.> I didn't have any directory sqllib (like on windows platform) after IBM DB2 Client installation, is it normal ? 3.> Do I need to install another software like iODBC ? Thanks. Jerry
