Description:
------------
This patch (against 5.3.8) adds a new php.ini directive to specify the path for the temporary files.

Why:
If, for security reasons, every user is only allowed to use their own home directories, it's not possible to specify their own tmp dir (e.g. "/home/user/tmp"). The directory for uploading and session can already be specified. Since all users may use the same php.ini (different [HOST=domain] entries, [1]) it's not possible to set the environment TMPDIR variable, because it would affect all users.

[1] http://php.net/manual/en/ini.sections.php

Test script:
---------------
ini: system_tmp_dir = "/home/user/tmp"

php: var_export(sys_get_temp_dir());

Expected result:
----------------
'/home/user/tmp'

Actual result:
--------------
'/tmp' (depends on system configuration)

Any chance of getting this backported to 5.3 and 5.4?
 [2013-07-11 13:54 UTC] mail+bugs dot php dot net at kazik dot de 
The 5.5's pull request is here:
https://github.com/php/php-src/pull/262

It should be easy to patch 5.4 and 5.3 with that or a slightly modified version 
(there a older patches for 5.3 and 5.4 available).

Whether this should be backported or not is not for me to decide.

So, feel free to port.
