This is intentional behaviour, there are times when you want a copy of a reference and there are times when you want a reference to a reference. For instance consider the following: $foo1 = $foo2 = $foo3 = new a(); $foo2 = new b(); If these were references to references instead of copies of references then $foo1, $foo2, and $foo3 would all now refer to the newly created b object. Cheers, Rob.
OK I'm pretty clear on it, but now I wonder: is variable assignment (=) the only place where the Zend Engine will copy a reference instead of reference the reference?
