Hi.
The workaround does not work here because the serialize() function is
nt canonical. That is two equivalent objects will not come out the
same. E.g...
serialize(array('a' => 'A', 'b' => 'B'))
...is not the same as...
serialize(array('b' => 'B', 'a' => 'A'))
An object ID misses the mark. I am trying to compare two different
objects for equality, that is the same value. Having unique IDs just
ensures they are different objects.
I am completely defeated by the Zend engine at this point. I have had
to come up with some tortuous workarounds involving dependency
injection which I would love to do without. Not least because it causes
me to keep references lying around, defeating the PHP garbage collector.
Makes any pattern which treats objects as messages rather problematical
for example.
yours, Marcus

There is a workaround for this problem:
Serialize the references you want to compare, and compare their
serialized versions.
Or - give your Objects id's and compare their references by their
id's.
Hope this helps.

This one is for the Zend mastahs... but I'm not sure if this is very
easy to fix.

If you don't want to test the latest version, we can't help.

Hi...
Well thanks for the standard response in an attempt to stall. I had
enough trouble getting version 5.01 onto my Mandrake 9 box without
going through the whole thing again with an experimental version, and
then having to uninstall it. It would take several hours (possibly
days) out of my time, but for a developer with a CVS snapshot installed
it would take seconds. I could hardly have made the code shorter.
So in short, no thanks. Unless perhaps you have information that this
part of the code base has been worked on with respect to this issue?
yours, Marcus
