how to fiond out if an object is a reference

[jstaerk]

Hi there,
I'm in php 4 and i use objects, despite planning very carefully, there seems to be a bit of code that does not use a reference to an object (as it should be) but it copies the object (probably with "=").

is there any way to find out if an object is a reference or alias to another object or a identical copy? I mean, the ===-operator does not work (returns equal in both cases), and i tried some other things.

A function, that would return the same value for a varaible and it's references and another value for identical copies would be great, but there is no such thing, is there?

thanks,
Jochen

im wondering if u could use the size or the count of the variable?

One of the user notes in the manual section on references gives
this link. Maybe that will help.

Hi Weedpacket,

it's playful...it's cruel... i like it.

Thanks, that's wht I was looking for. It doesn't even generate a notice warning.
(I don't think adding members at run time is good style, but it is good for a test).

bye
Jochen
