global $GLOBALS;

Anon

I need access to the GLOBALS array in a function. I don't need access to the variables itself. Things like extract($GLOBALS); doesn't help!
Because what I need is: $GLOBALS=$MyArray;
The Problem: global $GLOBALS; doesn't work in any program. In smaller tests it works fine, but in larger programs after global $GLOBALS; the array $GLOBALS is unset in the function.

So... let me get this straight.. you want to make the global array $GLOBALS, global?

The $GLOBALS variable is always available in the local scope of a function,
you do not need to redeclare or make it global or whatever...

Erm... Say what???

Yes - I want to make the global array $GLOBALS global in a function. But not to access the variables! I would like to set up $GLOBALS totaly new with $GLOBALS=$MyGlobals;

Oh my, three posts from the same IP...
No, it's not me, vincent "the bot", posting under three accounts, it's my dear collegues at work who have been infected by the PHPbuilder virus....

That is wrong! You can't declare the real $GLOBALS variable with $GLOBALS=$MyGlobals; if you not stated the $GLOBALS variable as global. So 'global $GLOBALS;' is important to do your own things with the $GLOBALS array.

Hmm... that wasn't what i said.
Anyway... it definitly is a NO NO to do it... but here's the code:

while (list($key,$val)=each($GLOBALS))
{
unset($GLOBALS[$key]);
}
$myglobals=array("hello"=>"hoi");
while (list($key, $val)=each($myglobals))
{
$GLOBALS[$key]=$val;
}
unset($key);
unset($val);
echo $hello;

You are deleting the variables in $GLOBALS. Yes this is definitly a NO NO to do it. And I don't like to that. Again: What I need is only the $GLOBALS=$MyGlobals; statement. In my $MyGlobals are exactly the same variables as in $GLOBALS itself. I don't need workarounds because I have already a working workaround. I would like to know: Why global $GLOBALS; in one program works and in an other program not. And 'global $GLOBALS;' is important to access $GLOBALS direkt like $GLOBALS=$MyGlobals; in a function.

For what this should be usefull? Well, its a variable sandbox:

$MyGlobals=$GLOBALS;
DoFunction();
$GLOBALS=$MyGlobals;

But this example doesn't work:

If we would change $GLOBALS in DoFunction(); then the $MyGlobals is also changed.
$GLOBALS=$MyGlobals; doesn't work correct in each programm because we need the global $GLOBALS; and now start to read my posting from the top again.
Solution is simple: read the $GLOBALS array with foreach() or like your example and build a new array.
Solution is also simple: read the $GLOBALS again with foreach() and set it with the value from $MyGlobals or unset it when the key doesn't exist in $MyGlobals.

But the better way is:

global $GLOBALS;

read $GLOBALS array into $MyGlobals array

with foreach()

DoFunction();

$GLOBALS=$MyGlobals;

Works fine in some programms and don't work in others. Because the global $GLOBALS; statement doesn't work in each environment.

You should never f*ck with the $GLOBALS array in this manner.

Instead, use objects. that's what they are there for.

If you don't like to understand.

In my version I do only:

read variables from $GLOBALS to memorize the keys
unset($variables) from global scope that are not memorized

There is nothing special! This must be possible and 100% allowed in php.

The other way $GLOBALS=$MyGlobals; is indeed a more special thing. But this isn't the topic of my question. The question is again and again: Why global $GLOBALS; in one program works fine and in an other program fails?

But in the meantime have the answer from an other much better german php board.

Objects are not usefull because I don't know today which third party code I want to include.

I'd like to understand, but you don't seem to be able to make us understand.
Not attacking your english ofcourse.

1. read variables from $GLOBALS to memorize the keys
2. unset($variables) from global scope that are not memorized

This is the first time you mention that.
Indeed that is nothing special, but it's also a very dumb thing to do.

The other way $GLOBALS=$MyGlobals; is indeed a more special thing.
But this isn't the topic of my question.

It has been from your first post:
-- Because what I need is: $GLOBALS=$MyArray;

The question is again and again: Why global $GLOBALS; in one program works
fine and in an other program fails?

It probably always fails, but in one case you don't notice.

But in the meantime have the answer from an other much better german php > board.

"Never mind, I found it on a better board". That's the standard answer that everyone gives when he doesn't understand or like the answers he gets here.

You do know what objects are?
