Description:
------------
Hi,
http://de2.php.net/manual/en/ini.core.php#ini.register-globals
says register_globals is changeable PHP_INI_PERDIR.


However the faq entry about "Emulating Register Globals"
http://de2.php.net/manual/en/faq.misc.php#faq.misc.registerglobals
uses statements like:
ini_set('register_globals', true);
and
ini_set('register_globals', false);

The purpose of this statements isn't really clear.

The usage of this ini_set statements is conflicting with the explanation of register_globals in the manual and where and how this setting can be changed.
 

Kind regards
Friedhelm

This bug has been fixed in the documentation's XML sources. Since the
online and downloadable versions of the documentation need some time
to get updated, we would like to ask you to be a bit patient.

Thank you for the report, and for helping us make our documentation better.

It's for telling the rest of the script that globals are (not) registered (if tested with ini_get).

Hi,

The manual says very clear, that you cannot change register_globals with ini_set, because it is changeable PHP_INI_DIR:

register_globals	"0"	PHP_INI_PERDIR	PHP_INI_ALL in PHP <= 4.2.3.


Conclusion: using ini_set('register_globals', 'what_ever_value') has no effect, no?


Kind regards
Friedhelm

You are absolutely right, sorry for the confusion. I removed the ini_set('register_globals') from FAQ.

It does have some effect in regards to sessions (at least it used to, not sure since 4.2.3). And I assume the author of that FAQ put it there in case the script uses ini_get('register_globals') somewhere else in which case the script knows it's been polluted (behaving like it's on). But to avoid confusion, I also think it should be removed.

I also thought that <?php ini_set("whetever", "foo"); echo ini_get("whatever"); ?> prints "foo" thus I documented why ini_set was called in FAQ first. But it's not true (at least in 4.3.10 and 5.0.3), ini_set() works only with PHP_INI_USER.
