Description:
------------
We have all or .htm and .html (as well as .php, ...)
files go through php. When a person creates a web
page and saves the file with the wrong permissions so
that they are not accessable by the httpd daemon, instead
of giving an error like 403, the page returned is:

Warning: Filed opening '/users/johndoe/public_html/x.html'
for includsion (include_path=".:/usr/local/etc/php') in
Unknown on line 0

The file (unix) is mode 600. If we change it to 644, there
is no problem. Should not this be returned so that an error
handler can handle it, such as 403 code?

Please note the above error came from:

http://www.gpc.edu/~johndoe/x.html

(this is not a real link, but that is the format of
the link.)


Reproduce code:
---------------
Not (php) code related - file system permission.

Expected result:
----------------
The expected result is that this would be caught by 403
error code.

Actual result:
--------------
It gives a php result that it can't include the file.

Is there a separate php error code list we should
capture in config files? Basically, we want a cleaner
way of handleling such errors so that it makes more
sense to the visitor to a page, such as the 403 error
for normal apache would do.
