Bug description: Incorrect result using references and objects
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).
