deployment - PHP : Virtual machines VS __FILE__ resolving symbolic links? -


i'm using existing php software makes extensive usage of __file__ magic constant, require bootstrap files, among other things, example: 

require dirname(__file__) . '/path/to/config.php';

right have several websites on same server running software.

all websites have copies of files, works, centralize "common" files (classes, controllers, etc...), to:

  • reduce amount of files
  • simplify deployments

at first, thought using symlinks "common" files, simple folders "specific" files:

config classes -> /path/to/common/classes controllers -> /path/to/common/controllers ...

... problem __file__ resolves symbolic links

since php 4.0.2, __file__ contains absolute path symlinks resolved whereas in older versions contained relative path under circumstances.

it means using constant resolve pathes relative "common" files, not want.

i know can use $_server['script_filename], don't want modify code of software i'm using, unmaintainable.

is there other way achieve ?

maybe using virtual machines (one each website) sort of shared folders ? (i'm not expert @ all)
