#32334 [NEW]: __set acts unexpected with variable variables
From: mk at peytz dot dk
Operating system: Linux
PHP version: 5.0.3
PHP Bug Type: Zend Engine 2 problem
Bug description: __set acts unexpected with variable variables
Description:
When setting variable variable values on a instance of a class with an
overloading __set function changing another instance variable goes wrong.
(I'm reporting it for version 5.0.3 because the current cvs snapshot would
not compile.)
Reproduce code:
---
http://dev.peytz.dk/~mk/setter.php
?php
class Setter
{
private $_fields = array(); // the data fields
private $_changedFields = array(); // list of changed fields
function __set($name, $value)
{
// set value
$this-_fields[$name] = $value;
// add to list of changed fields
$this-_changedFields[] = $name;
}
}
$foo = new Setter;
$foo-a = 1;
$var = b;
$foo-$var = 2;
var_export($foo);
?
Expected result:
class Setter {
private $_fields =
array (
'a' = 1,
'b' = 2,
);
private $_changedFields =
array (
0 = 'a',
1 = 'b',
);
}
Actual result:
--
class Setter {
private $_fields =
array (
'a' = 1,
'b' = 2,
);
private $_changedFields =
array (
0 = 'a',
1 = ' ',
);
}

Can't reproduce *your* behaviour with latest 5.0.x 5.1 CVS.
But some issue really exists, as I get NULL instead of 'b' with both
branches.

But the problem persist with the CVS snapshot (which now compiles
again).
