If I have two object in php, how does the == operator work? E.g. $obj1 = new Object(); $obj2 = $obj1 what is the result of ($obj1 == $obj2)? What about this? $obj1 = & new Object(); $obj2 = & $obj1 what is the result of ($obj1 == $obj2)? Does the == operator do a memory location comparison for objects, or does it actually comare the values within the object?

Is there any way to check whether > $key came back as an int or a bool? Try if ($key === false) { // false it is } The third '=' compares the two to see that they are also of the same type. Or if you just want to check the type and not the value, check out the function http://www.php.net/is_bool and the related functions listed on that page.
