Hmm..
Funny I was having this same problem yesterday and wanted to post.
Here's My question, a variable is not actually global is not
actually global until I make it global through "global $make_this_global"
and then I can assess it using $GLOBAL[$make_this_global].
Another method would be to "global"ise it on demand by writing a
little function. (like Rasmus)
I did it like this -->
---create_globals.php------------
function create_global($passed_variable)
if (isset ($GLOBALS[$passed_variable]))
{
return $GLOBALS[$passed_variable];
}
---------------end-----------------
--------config.php------------------
$page_title = "Page Title of Web Page"
---------end------------------------
----------index.html----------------
require_once ('create_globals.php');
$local_variable = create_global( 'main_title')
echo "My Page Title is".$local_variable;
--------------end---------------------
Hence This way I can make it global-on-demand.
Maybe a better way to do it would be to
---------------config.php-----------
global $page_title = "Alternative Way"
----------------end-----------------
then I can ->echo "This is an ".$page_title; and it'll come out as -> "This
is an alternative way"
The only problem here would be the "EXTRA" typing involved. The other
problem/question is, will there be a speed tradeoff? If I were to global'ise
everything at the 1st place, would it be faster than jumping in and out of
create_global() and going through $page_title & whatever other variables? (I
want to make all global configurations in this file so it'll be easy to
change)
Any help is appreciated.

Hi,
If the file you are including is of your own authorage (I know that
isn't a word, but whatever :), just refer to global variables always as
an index of the $GLOBALS array. This is good practice anyways for any
file that might be included by another user, for exactly this issue.
I have a file that could be a global include or not in my project, and
making sure every global variable is referenced as $GLOBALS['varname']
fixed it for me without any fancy code (although Rasmus's code is very nice)
Regards,
Greg
