SOAP web service to call a Code Igniter function from teh soap server file
===

I have made a SOAP API in core PHP and is placed in the root folder and the site is developed in Code Igniter.<br/>
Now i want to call a function developed in a controller file of the CI framework from, the SOAP Server file which is not a part of CI. It is infact developed in core PHP.
<br/><Br/>Is there any way to call that CI function from the CORE php SOAP server file which is placed in teh root folder of the project and not a part of CI framework?
