Description:
------------
First of all: Sorry for my bad english.

Initial situation:
var1 = object
var2 = object itself way var 1 (other properties)

Object has a method which requires a normal parameter passing (no call by reference) as a "typing" is selected the object itself.

var1-> method (var2);

expected:
within method a copy of var2 is used

Currently (in all PHP versions)
It is used a reference inside the method, although with no parameter declaration Referez was desired.

See Test Script (output should an HTML table with different contents in the lines be, instead of the same content)

Objects do not get copied since PHP 5, while in PHP 4 they worked like you describe. This is not references but they are similar.

It is very, very much intentional.

If you need a copy of the object then you can clone it.
