<?php
$a = new Object();

// $b is a new reference ("link") to the object in $a and not(!) a copy

$b = $a;

// Now we change something in the object

$b->setName('foobar');

// This will return the same name wich was just set using $b since
// $b is just another reference to the object originally assinged to $a

$a->getName();
?>

If you need a copy of an object, you need to use the "clone" keyword:

<?php
$a = new Object();

// This will create a copy of the object in $b
$b = clone $a;
?>
