I am working on PeopleSoft integration that request PHP runs on web server. We are on WebLogic 10.3 ( IBM AIX on POWER Systems (64-bit) ). Can someone share clear cut steps to install/configure PHP on web logic? I appreciate your help.
With OHS, you might get some joy from the OHS section in http://www.oracle.com/technetwork/topics/php/026973.pdf (search for "Oracle HTTP Server") and from https://blogs.oracle.com/opal/entry/building_php_53_with_oracle_ht
Steps for iPlanet would not be too dissimilar.
Otherwise, look at using a web server plugin such as described in http://docs.oracle.com/cd/E14571_01/web.1111/e14395.pdf

PeopleSoft customers don't use OHS. Some customers just run WebLogic directly, with browsers connecting directly to WebLogic. No reverse proxy (OHS/webtier, etc) at all. I don't recommend anyone run this way, but it is the default configuration and is easy to get started. I suspect that is why the request was to run PHP directly out of WebLogic.
Those that configure for SSL (and all customers should run SSL) or that run on port 80 use third party load balancers and SSL accelerators. Some use httpd with the Weblogic Apache bridge.
