class scope::

[php]
class database{
function __construct(){
$this->connect_id = mysql_connect('localhost','root','');
if($this->connect_id){
if (mysql_select_db('dbname')) return $this->connect_id;
else return $this->error();
}else return $this->error();
}
function query($query){
if ($query != NULL){
$this->query_result = mysql_query($query, $this->connect_id);
if(!$this->query_result){
return false;
}else{
return $this->query_result;
}
}else{
return false;
}
}
}
[/php]I want to access query from other class like this:

[php]
database::query("UPDATE users SET ....");
[/php]but I can't access it, any ideas? I think I should update database class because I read somewhere that I can't access $this-> from other class..

edit: I know about this solution
[php]
$db = new database();
$db->query...
[/php]and it works, but I don't know, I don't like when I need to "recreate" class..

re: class scope::

Have a look to singleton pattern in PHP.
It is exactly what you need. The main idea it that you don't need to create an instance of dbConnection class every time you use it. It can be done via static variables&functions. Try google for it.

re: class scope::

hm, my next solution is that I use

[PHP]
$GLOBALS['db']->query(....
[/PHP]

as $db is already created. Would this be optimal solution?

re: class scope::

hello again

what I did is I created new class someclassname, which extends database class. Then we I construct it, I also construct database class suing parent::__contruct(); and everything works :D

only problem is how do I access parent class or the parent class? For example if I have new class somenewclassname extends someclassname, how do I access database class?
