Same as bugs #52065 and #44901. Reproduced on Windows.

some file function (eg, is_file) calls the C functions:
-> php_stat
-> php_check_specific_open_basedir(_ex) [1]
-> expand_filepath(_ex)
-> virtual_file_ex
-> tsrm_realpath_r [2]:
Unable to access /home/my_file.txt/whatever, [2] next checks that /home/my_file.txt exists *and is a directory*. Since it isn't a directory, everything fails all the way back up to [1], which then, assuming it was a problem specifically with the open_basedir restriction, issues the warning.

this problem still occurs in 5.3.5

I setup my machine as described in this bug and changed my /etc/php.ini so that open_basedir = /home/, mkdir /home/my_file.txt and did a touch /home/my_file.txt/whatever. I then ran this script

<?php
var_dump (is_file("/home/my_file.txt"));
var_dump (is_file("/home/my_file.txt/whatever"));
?>

and got this

bool(false)
bool(true)

Is there another change I need to make to php.ini or something I'm missing?

apart from you not reproducing the bug correctly (my_file.txt should obviously be a file, not a directory), this seems to have been fixed by now.

I suspect this to fix it:

http://svn.php.net/viewvc/php/php-src/branches/PHP_5_3/TSRM/tsrm_virtual_cwd.c?r1=264931&r2=264932&

My apologies. But it says "directory: /home/my_file.txt" so I the directions were a little unclear. sry

Still occurs in 5.3.5, more than annoying when you have a lot of vhosts with 
open_basedir + error_reporting E_ALL

Still occurs in PHP 5.3.6.

to replicate:
<?php
error_reporting(E_ALL);
ini_set('display_errors', 1);

echo 'testing open basedir problems <br />';

// append text to current directory name which should be the dir of open_basedir to trigger open_basedir warning
echo 'checking ' . dirname(__FILE__) . 'test <br />';
var_dump(file_exists(dirname(__FILE__) . 'test'));

// no warning should occur here whether index.php exists or not
echo 'checking ' . dirname(__FILE__) . '/index.php <br />';
var_dump(file_exists(dirname(__FILE__) . '/index.php'));

// if index.php exists a open_basedir warning will be thrown
echo 'checking ' . dirname(__FILE__) . '/index.php/test <br />';
var_dump(file_exists(dirname(__FILE__) . '/index.php/test'));

Given:

dirname(__FILE__) . '/index.php/test'

I suppose that index.php is a file, right?

No feedback was provided. The bug is being suspended because
we assume that you are no longer experiencing the problem.
If this is not the case and you are able to provide the
information that was requested earlier, please do so and
change the status of the bug back to "Open". Thank you.

Still reproduced on 5.4.17.20130704:

Still said about open_basedir restriction when checking the path contains real file instead dir in the middle of the path.


is_file('/home/my_file.txt/file');

where /home/my_file.txt is a real file.

This is a duplicate of bug #52065.
