Php :: Make Xampp Environment Behave The Same As Remote Shared Hosting Environment?

i don't know how to say that in technical terms. and i think this is the reason to why i cant get good answer from Google.i have xampp on my local winxp machine. i use it for developing websites locally then upload these files to my clients shared hosting accounts.

the problem that in 2 years i have always found differences between how xampp works and how the web server work.some code work locally but dont remotely and the opposite. also flash behave differently on xampp than the remote web server.is there is a way i can get the server configuration and use it with xampp like get the server php.ini and use it with xampp?
