Description:
------------
The only configuration option for setting the temporary directory for normal operations is the upload_tmp_dir option. As such, functions that rely on the temporary directory should respect the upload_tmp_dir option to ensure that true separation of concerns between virtual hosts can be achieved. This is particularly important when also using open_basedir.

Note that the following line is correctly located in the vhost config:

php_admin_value upload_tmp_dir "/www/myvhost/tmp"

Test script:
---------------
<?php
// Create a temporary file in the temporary 
// files directory using sys_get_temp_dir()
$temp_file = tempnam(sys_get_temp_dir(), 'Tux');

echo $temp_file;
?>

Expected result:
----------------
/www/myvhost/tmp/TuxDRhRIg

Actual result:
--------------
/tmp/TuxDRhRIg

Additionally, enabling open_basedir results in FALSE and triggers the following warning:

PHP Warning:  tempnam(): open_basedir restriction in effect. File(/tmp) is not within the allowed path(s): (/www/myvhost/)

Thank you for taking the time to write to us, but this is not
a bug. Please double-check the documentation available at
http://www.php.net/manual/ and the instructions on how to report
a bug at http://bugs.php.net/how-to-report.php

The function is designed to return the location of the temporary directory, not 
the file upload directory.

@iliaa: Please tell me how to set the location of the temporary directory using php_admin_value or php_value, as I do not see a way of setting the temporary directory at the vhost level in the documentation. If that is not currently possible, please reclassify this as a valid feature request. Thank you for your time.
