?????
Now I am really confused.
Im running Fedora Core 8 / x64, php 5.2.4, and i have the, by your
statement, incorrect result
I understand this has changed and I understand the implication (review
all our code which at this point amounts to several million lines of
code :( )
I also understand that i need to 'clone' an object. Shame that PHP4
doesn't understand this keyword and throws an error; so much for writing
universal code.
Thank you for all your comments and views.

I am running this on 64bit linux, and on 32bit as well. I get the same
correct result.

Thank you scottmac, this helps a bit.
Should I consider PHP5/x64/linux bugged then for NOT reflecting this
behavioural change ?

The behavior changed between php4 and php5. When you pass around an
object it uses the same instance.
The clone keyword will let you duplicate an object.

Bogus ???
$two = $one;
is not the same as
$two =& $one;
PHP4 all platforms understand this
PHP5 on x64 understands this
so, if this is bogus, how do I make a copy of an object and not have
changes to the copy affect the original object?
Arrays are unaffected as are normal variables
So, again, if this is bogus, the following is then true;
the assignment operator ' = ' makes a copy of a variable on the
righthand side EXCEPT when the righthandside is an object
This does not make sense.

Tested versions:
php 5.2.4 / fedora core 8 / x64: no problem
php 5.2.6 / fedora core 4 / x32: bug occurs
php 5.0.5 / fedora core 4 / x32: bug occurs
php 5.2.4 / win32 : bug occurs (downloaded the binary and executed
script)
php 5.2.6 / win32 : bug occurs
php 4.4.8 / win32 : no problem

Thoughts:
Has this behaviour changed in php5? why does ' = ' do the same as ' =&
' ?
Why do 2 different FC4 servers have this problem and an FC8 does not?
Could this be a difference in 32 bit and 64 bit versions?
