Hi there,
no much simpler. I do not need to assign the value from outside
the class. This
is just inside the class. I have the login data for a database
saved in a file
and would like to use simply the variable $DB_login inside this
class.
This does not work:
$this->db_username = $DB_login;
That's the right way to do it.
What are you seeing?

The following code:
class search_helper extends AjaxACApplication
{
var $db_username;
$this->db_username = $DB_LOGIN;
Try it like this:
class search_helper extends AjaxACApplication
{
var $db_username;
...
function SetDBUsername($db_username) {
$this->db_username = $db_username;
}
If you want to set a default:
var $db_username = 'xxxxxxxx';

That looks like to much for just assigning value to a variable?!
I would need 4 of those functions just to set the value of 4 variables
to a value saved inside another variable. If I do understand you
right, I would
also have to call that function inside the class to get that value set?:
function SetDBUsername($db_username) {
$this->db_username = $db_username;
}
SetDBUsername();
Is there not something more easy than that. For example $var1 = $var2;

You're right...
This is the wonders of OOP. Some people see this as nice because only
your class has direct access to set your variables...so inside your
'set' function you can do validation, formatting, etc... to make sure
you are setting the variable to a proper value....
Some people like the control, others think it is too much work with
little gain, this is largely a political issue though, so we won't get
into it too much.
Basically if you want to use classes you have to play by the rules of
OOP. To set and get a member variable within a class you need to define
a function to do so.
