Bug description:  realpath() returns null for the apache alias directory

Description:
------------
I try to use the realpath() call to get the absolute file path for a file.
The file is located on the directory that was specified as a apache alias
directory. Following is the alias set up in Apache httpd.conf:

    Alias /tctv/testimages "//192.168.1.125/tcshare/Logs/images"

    <Directory "//192.168.1.125/tcshare/Logs/images">
        Options Indexes FollowSymlinks MultiViews
        AllowOverride None
        Order allow,deny
        Allow from all
    </Directory>

Here is the php snippet to make a realpath() call:

<?
...

echo "realpath=" . realpath("./testimages") . "<BR>";

...
?>

I do expect it returns "//192.168.1.125/tcshare/Logs/images", however, it
returns null.

I will appreciate if someone can help me on this.

        Allow from all
    </Directory>

Here is the php snippet to make a realpath() call:

<?
...

echo "realpath=" . realpath("./testimages") . "<BR>";

...
?>

Expected result:
----------------

returns null.
