class myClass {
private var $_001;
private var $_002;
private var $_003;
public function access_var($var) {
return $this->$$var;
}
}
$cs = new myClass;
$cs->access_var('_001');
// Done
BTW, please make certain that you aren't really naming your variables as
$001, $002 and $003. Those are bad variable names, as PHP only allows
for variables beginning with letters and '_' characters (what I did above).
