What do you say “Yahoo Job Interview Questions: Part 2″?

1) Operator == is used to check two objects are same or not.
So if 2 objects have same property values and are instances of same class then it returns true else false .

2)operator === is used to check if 2 variables actually refer to same object instance.
ex:- class abc { }
$a= new abc();
$b=&$a;
then it returns true .

3) example of something that will give true for == and not for === is
clone() function.
cont …. above program

$c= clone($a);
then ($a==$b) returns true ,
but ($a===$b) returns false.
