Help with a php line

[Shayden85]

I have this:

if ( file_exists($checkfilename) ) return str_replace( $site_dir, trailingslashit, $checkfilename ); 

It gives me the wrong adress.

Lets say it gives me a adress that looks like this:

/home/user/public_html/

but i want(need) it to look like this

/home/user/domains/website.com/public_html/

How can i do this ?

if ( file_exists( $checkfilename ) ) return str_replace( $site_dir, trailingslashit( $site_uri ), $checkfilename );

Didnt work.

Thats how the code looked like first but it still doesnt show the right adress because in the /home/user/public_html/, then public_html are a link that goes to /home/user/domains/website.com/public_html/

Ok, so i fixed it in a retarded way.

I made link that goes from the wrong folder to the right folder. >.<
