If you need to configure your xampp installation (on winXP) to connect to the oracle

- first you need to download oracle basic instant client for windows

- After unzipping the instant client on a selected directory (i.e. c:/instantclient_11_1) you need to copy all dlls from this directory to “xampp/apache/bin/”

- Add instant client directory to windows system variable’s path : follow Start -> Control Panel -> System -> Advanced -> Environment Variables and edit PATH in the System variables list

- now open up php.ini from “xampp/php” and remove semicolon from this line “;extension=php_oci8.dll”

all you have to do is restarting apache and you’re all set

here is a nice document with more general detail about installing php and the oracle instant client for linux and windows

As of php5.2 you can use APC to create progress bar for your file upload
