7.6. Assigning Object References

7.6.3. Discussion

When you do an object assignment using =, you create a new copy of an object. So, modifying one doesn't alter the other. But when you use =&, the two objects point at each other, so any changes made in the first are also made in the second:

$adam = new user;

$dave =& $adam;

The values in $adam are equal to those of $dave.
