I'm no guru, but here goes anyway ...
default variable values can simply be set with a "var" statement:
var $somevar1 = "value1";
var $somevar2 = "value2";
or with a "set" function:
var $somevar1;
var $somevar2;
function setsomevar1()
{
$this->somevar1 = "value1";
}
function setsomevar2()
{
$this->somevar2 = "value2";
}
One "set" function could probably query a database and set all your vars
in one go:
function setallvars()
{
// query db, get values
$this->somevar1 = "value1";
$this->somevar2 = "value2";
}
Amyway, you could then call the set var functions from within your
constructor:
function issue()
{
setallvars();
or
setsomevar1();
setsomevar2();
}
Just a suggestion. No doubt someone will correct me if I'm wrong ... I'm
new to OOP myself.
