When Im talking about something like this would come in handy
obviously doesnt work! The paramter null could be added, to get
desired result but to be programmatically correct:
class MyOverload{
function __construct($Foo) {
$this->Foo = $Foo;
}
// overload the constructor
function __construct(String $Foo, String $Bar){
$this->Foo = $Foo;
$this->Bar = $Bar;
}
public function doSomething(){
if($this->Foo != null && $this->Bar == null){
return $this->Foo . " needs a partner";
// do something with Foo
}elseif($this->Foo != null && $this->Bar != null){
return $this->Foo . " and " . $this->Bar . " are partners";
//do
something with Foo and Bar
}
}
private $Foo;
private $Bar;
}
$obj = new MyOverload("Mary");
print $obj->doSomething();
