PHP_INI_SYSTEM and httpd.conf

I can clearly set the PHP_INI_SYSTEM option in the httpd.conf.
As stated in http://php.net/configuration.changes you should use the
'php_admin_xx' directive instead of 'php_xx'.

AFAIK, those options marked with 'php.ini only' were considered too
expensive to be set at run-time (they are hard-coded in the ini updater
script - phpdoc/scripts/iniupdate).

Hello core folks.

Please see this table:
http://php.net/manual/en/ini.php#AEN189095

As long as I can remember, the manual has said that PHP_INI_SYSTEM is
settable in httpd.conf.

I just ran some tests, and it seems that this is not the case. Seems these
are only settable in php.ini.

The manual even goes far as to distinguish between "php.ini only"
(disable_classes, for example), and PHP_INI_SYSTEM.

So, am I just missing something, or is the manual wrong?
Could someone clarify in unambiguous terms the credentials for changing a
setting that is PHP_INI_SYSTEM?

(sorry for the crosspost)

Thanks,
S
