------------
The PHP docs site manual (http://docs.php.net/manual/en/index.php) 
displays PHP notices. 

It only happens on the index.php page and only when using my Mac.

Visit http://docs.php.net/manual/en/index.php 

using Safari or Firefox browser on Mac OS X

Expected result:
----------------
Expect to see a clean page, no PHP notices.
