Correct link in PHP error text

On my localhost if I'm working on a project in http://localhost/project_name/ whenever I get an error or a warning it contains a link to the function but the link points to the wrong place, e.g. it points to http://localhost/project_name/function.rename

I have the many-HTML manual in http://localhost/php_manual/ is there a setting by which I instruct PHP to point to the correct place when it issues an error or a warning?

see docref_root
