Description

Typo3's install tool told me that safe_mode is on, while I was sure that it was off (also verified using phpinfo().

I pinned down the problem - it has to do with doing PHP settings using php_admin_value / php_admin_flag apache configuration directives.

Testcase:
echo "safe_mode status: " . ini_get('safe_mode');
if (ini_get('safe_mode')) { echo " ACTIVE"; }
?>

The result depends on the apache configuration you use to switch off safe_mode

Result with php_admin_flag safe_mode off (or without overriding php.ini settings at all)
safe_mode status: 0 <-- expected

Result with php_admin_value safe_mode off
safe_mode status: off ACTIVE <--- NOT expected

The safe_mode check should check for "on" and true.

- Add php_admin_value safe_mode off to your apache configuration, reload apache
- check safe_mode status in the install tool
(tested using PHP 5.1.2 on SUSE Linux 10.1)
