Re: [PHP] ini_set() broken?
You cannot set register_globals at runtime via ini_set(). The documentation goes off the PHP4 source which is, to put it simply, a little wrong. The PHP4 source says register_globals is PHP_INI_ALL when in the real world it isn't. .htaccess is as close as you'll get. The ini_set() docs are autogenerated and this issue is being looked into. The correct docs on this are now in phpdoc CVS and will show up soon. In short, don't attempt to set register_globals at runtime as explained by a few in this thread, it won't fully work as expected.

Re: [PHP] ini_set() broken?
Well, you can set it at runtime, it just won't do what you might expect. That doesn't mean that it may not be useful to be able to set it at runtime. If, for example, you have register_globals off and you write an auto-prepend script, or even just a normal snippet of code that you insert into some other app at the beginning that emulates register_globals, then you may want to set register_globals = on at runtime so that any subsequent checks by the app will behave correctly. -Rasmus On Mon, 8 Jul 2002, Philip Olson wrote: You cannot set register_globals at runtime via ini_set().

Re: [PHP] ini_set() broken?
Hello Rasmus- How do you suggest ini_set() document these differences? Maybe the table at ini_set() could use another column, for descriptions and notes. Also, could you give a concise description for the differences between local and master values?

Re: [PHP] ini_set() broken?
master is the top-level default value set in either your php.ini if you have that file and have a specific value set, or ir not it is the PHP default for the config value. The local is the per-request setting set either in httpd.conf, .htaccess or locally in the script.

Yes, is it not obvious enough from just reading the code? I am showing that the ini_set() function is not working properly, as per the manual.

Before your code starts, there is a whole bunch of initialization that takes place in the script engine. It looks at its settings to see how it should behave. It gathers all the data that came from the web server (details about the user's request, etc.). It learns about its environment. It populates global variables. Having done these, it starts looking at your code. By this time it's too late to change the way those prior steps were taken. It's like waiting until the plane has taken off (i.e., execution of your code has begun) and then telling the flight attendant you wished it were headed to Chicago instead of Detroit. miguel -- PHP General Mailing List (http://www.php.net/) To unsubscribe, visit: http://www.php.net/unsub.php

Re: [PHP] ini_set() broken?
Hi
If you check with phpinfo() you will see that it is getting set to 1 or 0
but by the time your script is run it is too late for it to have any effect.
Also ini_get('registar_globals') will not return the current state.
I have no idea why, it looks like one of those undocumented safety features...

I just checked with an old PHP manual (probably 4.1.X) and
register_globals can only be set in PHP_INI_PERDIR PHP_INI_SYSTEM, ie
cannot be set at run-time. So either they changed the behaviour in 4.2.X,
or the latest manual is wrong.

No, but ini_get('register_globals') will :)

However, in the one instance where I used it, it returned 'Off'. My guess
is that it returns whatever was defined in php.ini. Thus if in php.ini you
had defined register_globals = 1, then ini_get('register_globals') returns
1.
It would be much better and less confusing if ini_get() returns values in
a consistent notation, eg for booleans it should either return (0/1) OR
(false/true).
Another gotcha that I've come across is when setting register_globals (may
or may not apply to other settings) in the apache conf file.
This does NOT work:
php_value register_globals On
Whereas this does work:
php_value register_globals 1
