New Comment:
It seems to me this issue is slightly different from bug #52065.
In this case, I'd say this is a documentation issue, namely that
it is not explicitly documented that the directories set in
open_basedir must exist.

I'll try again.
open_basedir is not the problem. It works correctly. What does *not* work correctly is what PHP does
when a file or directory does not exist.
if (path_exists_and_is_inside_open_basedir($path)) {
// (A) good: exists
} else {
if (open_basedir_is_enabled()) {
// (B) bad: "open_basedir restriction in effect"
// what if $path does not exist and is *inside* open_basedir!
} else {
// (C) good: does not exist
}
}

And how does it make not open_basedir problem? You are saying that I can't check if file/dir
exists because it might not exist.
Then how about mkdir()? or file_exists() or is_file()? mkdir() cant create directory because it also
does not exist?
cat a.php
<?
ini_set("open_basedir","/home/naox/public_html/test");
mkdir("/home/naox/public_html/test");
php a.php
Warning: mkdir(): open_basedir restriction in effect. File(/home/naox/public_html/test) is not
within the allowed path(s): (/home/naox/public_html/test) in
/home/naox/public_html/naox.vipserv.org/a.php on line 3

The issue is not open_basedir but that the functionality supporting is_dir() reports that the path
does not exist, and the reason for that is assumed to be an open_basedir restriction. If
public_html/test existed then you would not get this warning.

No, it does not exist but it should not matter.

Does public_html/test exist?
