OR you could control ur method and have optional arguments in ur
argument list and decide what to do according to that.
e.g. public function _construct($param1=0, $param2="", $param3=null)
{
if($param1)
....
if($param2)
....
if($param3)
....
}
$obj=new className(1);
//Or
$obj=new className(1,"hello");
//Or
$obj=new className(0,"","some_value");
Bottom Line:
Optional arguments might be a workaround lack of polymorphism sometimes !
