I have the following situation :

class B extends A {

Now I want to print this object

	***object***

<?php

$obj = new B;
print_r($obj);

?>

Does anybody know how I can print class A also ?

	***class***

(class and object are not interchangable concepts - yet
they are closely related :-)

you printed $obj which is an instance of B, which happens to
be a subclass of A. if you are interested to find out which classes
an objects is defined by try something like:

class A {}
class B extends A {}
class C extends B {}
$c = "C"; $classes = array($c);
while($c = get_parent_class($c))
	$classes[] = $c;
print_r($classes);



The above prints out:

B Object
(
    [var2] =>
    [var1] =>
)

Is this not what you expected?  You can't print out *just* the
properties of A.  If this isn't what you want, you shouldn't be extending A.
