Is there a generic Object in PHP?

Hi,

I would like to have a function that takes a generic object and takes
some action on this. Something like,

function AMethod(Object obj) {
DoSomeStufftotheObject;
}

then be able to pass various object types in. Is there a way to do
this in PHP? Do classes automatically inherit from a generic Object
like in Java?

Thanks.

No, there is no generic object in PHP. However, you don't need to
specify what kind of object is being passed, i.e.

function AMethod($obj) {

will take anything (not just objects). And from there you can figure
out what was passed.

Thank you.... my brain is stuck in JAVA mode and i forgot you do not
have to declare what is being passed in!

Thanks!

you can also do if(is_object($var)) to make sure its an object.

Just out of interest, is there any way to see what properties,
methods, constructs, etc the generic stdClass object has? Or maybe
it's documented somewhere?

Reflection could tell you, but the answer is much quicker: is has none (no
methods, no properties). This also is NOT the 'main class/object' from
which all other classes/objects are derived. It's just an empty container.
