#32453 [Opn]: Confusing faq about emulating register_globals

ID: 32453 Updated by: vrana@php.net Reported By: holliwell at gmx dot net Status: Open Bug Type: Documentation problem Operating System: n/a PHP Version: Irrelevant New Comment: 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. Previous Comments: ------------------------------------------------------------------------ [2005-03-25 17:07:21] philip@php.net 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. ------------------------------------------------------------------------ [2005-03-25 15:07:27] vrana@php.net You are absolutely right, sorry for the confusion. I removed the ini_set('register_globals') from FAQ. ------------------------------------------------------------------------ [2005-03-25 13:54:08] holliwell at gmx dot net 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 ------------------------------------------------------------------------ [2005-03-25 13:42:26] vrana@php.net 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). ------------------------------------------------------------------------ [2005-03-25 12:19:02] holliwell at gmx dot net 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.
