a question about the global valuriable

[faquir]

when I read some thread about the latest new section, I found a very interesting part is

global $database;

$result = $database->query($query);
$total = $result->numRows();   

I can not understand this coding writing, which I think it should be,

$database = new database();

then can access the methods in the database class.

could someone explain to me that, global $database; is the other way new a class?

Thanks.

is that wrong place I post?

Not the wrong place, I think

What I understand, and maybe I am wrong as well

By declaring the $database as global the allready existed $database is used so no new instance is needed.

Look at her for more info http://nl.php.net/global


Have fun,
