appending to include_path

hi, i'm hoping to find a way to append to the include_path set in my php.ini file. i've got several virtual servers that each require different include_paths which are defined using the php_admin_value line in my apache conf file. Since the documentation says that include_path is like the UNIX PATH variable, i assumed (or maybe hoped) that i would be able to use a syntax like this: php_admin_value include_path "$include_path:/some/other/path" unfortunately, it doesn't work. Is there a way to append to the path? -- ~darcy w. christ Elegant Communications Inc. 416.362.9772 x222 | 416.362.8324 fax
