integrating joomla with another php-program

[awakedesignstudios]

I have a joomla site, and I have another site that is fully dependent on its internal php functions.

 

(Im using Joomla for site design reasons, and Im using cashcrusader script for its php functions I need)

 

currently im displaying php-program inside joomla using wrapper iFrames...

 

My question is, can I get php code that works for the php program, to work inside a joomla custom html module.

 

For example, I have a mysite.com/joomla, and I have a mysite.com/php-site

 

i have an index.php file on php-site, that includes functions from imported php file

I want to make a custom html module in joomla, and copy my index code from php-site, into joomla, and have it operate the same way as if it was running straight from the php-site..

 

if that makes sense to u, and u have any idea of how to do this please help..

 

 

one solution i think may work is this...

 

install joomla,

then install php-program inside joomla directory.

 

then make custom html module, and copy exact code from php-program, but tell it to include the functions from /php-program/ directory which would be inside joomla directory.

 

seems like that would work, but im no php guru, any help is appreciated.  and i have no tried this yet.
