2486392 - Can I use .php in redirect pages hosted in SuccessFactors?

I would like to implement .php code in my SSO redirect page hosted in SuccessFactors to perform actions such as collect user data (e.g. IP) in SSO login.

Is it possible to implement .php elements in the redirect pages e.g https://performancemanager5.successfactors.eu/doc/custom/companyID/?
