Re: [PHP] How to access arrays from $GLOBAL?

2002-03-15 Thread bvr 



Maybe it makes sense to you like this:

$mtxt = $GLOBALS['mtxt'];

$mtxt === $GLOBALS['mtxt']
$mtxt[1] === $GLOBALS['mtxt'][1]

bvr.

 hmm.. the '===' operator, now that's weird ;)

Because in my mind (which I know is totally wrong in this instance, I'm just
explaining for your benefit) using:

$GLOBALS['mtxt'][1];

is like saying give me element 1 of the globals array when I was thinking
but I want element 1 of the mtxt array which is why I tried the various
combinations of mtxt[1] _inside_ of the globals[].

Hope that explains a little.

[PHP] How to access arrays from $GLOBAL?

2002-03-13 Thread Richard Davey 

Hi all,

I have a global array $mtxt that is created in my script.
I have a function from which I want to access a value from that array:

$mtxt[1] = Test;
$text = $GLOBALS['mtxt[1]'];

Except that gives me the Warning Undefined index;

I can use $GLOBALS['mtxt'] to access a global variable without an error,
just not a specific element of a global array.
Does anyone know the correct syntax for this?

I have tried:

$text = $GLOBALS[mtxt[1]];
$text = $GLOBALS[{mtxt[1]}];

But both fail too.

Cheers,

Richard

Fantastic :)

That's totally illogical but it works a treat.

I don't understand why you think it is illogical.  How else would you
dereference a multi-dimensional array?

Re: [PHP] How to access arrays from $GLOBAL?

2002-03-13 Thread Andrey Hristov 

IMO it is not weird. Think about $GLOBALS['mtxt'] as a pointer to array(it is not but 
this is a good example).
$GLOBALS is a hash list. So it has sub elements - zvals (internal _zend_value ). Every 
from these zvals can hold zvals. In C the
syntax is arFooBar[1][2], not arFooBar[[1][2]]

I am not nagging(not sure for the word) at you.


Best regards,
Andrey Hristov

RE: [PHP] How to access arrays from $GLOBAL?

2002-03-13 Thread Rasmus Lerdorf 

I am not sure there is any.  $GLOBALS is simply an array that contains
individual references to each global variable.

For example:

  $a = 1;
  $GLOBALS['a'] = 2;
  echo $a;

gives you 2

The best documentation is probably the basic explanation of how references
work.  http://php.net/references

Re: [PHP] How to access arrays from $GLOBAL?

2002-03-13 Thread Andrey Hristov 

to add that $GLOBALS has reference to itself but when used in non-function context. 
Try ?php var_dump($GLOBALS);? and ?php
function a(){ var_dump($GLOBALS); } a(); ?
