PHP and type of link

[soucer2k6]

I have a problem when I test a site in local

 

This site have a link in the form: www.mysite.com/index.php/another_file/function_name/funct_param

 

where:

another_file    =  is a php file that it wants to be execute

function_name =  is a function present in the "another_file"

funct_param    =  is a parameter for the "function_name"

 

The problem is when I test to navigate the site in local, this type of link NON function (the "another_file" is not execute and comes execute the index.php file). WHY? 

I suppose that the PHP or Apache configuration in NOT correct.

I have enable PATH_INFO in PHP but his value ( $_SERVER['PATH_INFO'] )  is null. WHY?

 

Enyone can help me?

 

thank you.
