GLOBAL or not GLOBAL ?

Anon

Does anybody know if "global" is good to use or not ? I have so many functions for my website and I begin to get bored to pass each time arguments...
In fact the question is: does "global" use a lot of memory ?

BTW, can I declare:
global $var1, $var2, $var3 ;

Or should I declare like this:
global $var1 ;
global $var2 ;
global $var3 ;

Thank you for your help !

if all your function need those same variables in same execution time, then sure why not use globals. i dont think there might be any concern of memory etc.

and yes, you can declare
GLOBAL $var1, $var2; etc

Great !
I talked about memory since I care so much of my professional website code (for example: first version (1999) weights 340ko and now its only 50ko for the same services!).

I am not sure I understand, but this is what I want.

1.php...

<?$a="eric";
global $a;
print $a?>
<br><a href=2.php>go to page 2</a>

2.php...
<?
print global $a;?>

I want to set a variable in 1.php and have it move from page to page. If the variable changes, I want it to change everywhere.

Any ideas??

Use a database to store the variables or use sessions.

Hi can u tell me the function of the word global

In my login.php file, I have this:

<?
require ("config.php")
global $sitecatid

In my config.php file, there isn't any reference to this variable sitecatid; but this word "sitecatid" exists in the sql file for the script.

I would like to know the function of this word: global

Thanks
