Shallow copying of objects and arrays bit you...

Will be fixed in PHP 5

Suspended (it could be called a 'feature' though...)

If you set a property of an object to a global variable, it is no longer possible to 
make a copy of that object! Every "copy" becomes a reference.  Example:

--/ snip /--

class foo
        function foo()
                $this->test = 'Test';
                $GLOBALS['test'] =& $this->test;

$obj1 = new foo();
$copyOfObj1 = $obj1;  // Should be a copy, but is reference

$obj1->test = "changed!";
echo $copyOfObj1->test.'<br>';

--/ snip /--

The result of this code is: "changed!" but it should be "Test".  $copyOfObj1 should be 
a copy of $obj1, but instead it acts like a reference.

If you unset $GLOBALS['test'] then it copies as it should.

This is a bug occurs in all versions of PHP4 on all platforms (from what I can tell).
