Status: Open
Bug Type: Scripting Engine problem
Operating System: Ubuntu
PHP Version: 5.2.7
New Comment:
When I said "except for zero." I really meant "except for an integer
starting with zero".
ie: 1234 will reproduce the error but 0123 will not.
For negative integers -1234 will reproduce the error but -0123 will
not, and neither will 0-123
Sorry for not stating this correctly in the first place.

Description:
------------
var_export(), get_object_vars(), and ReflectionObject do not recognize
or handle object properties correctly that are coerced from a
numerically indexed array or an array with string keys of any integer
except for zero.
ie: (object)array(1,2,3,4);
ie: (object)array('1' => 1, '-5' => 2, '3' => 3,
'-10' => 4);
Values seem to have no effect. There may be other functions/classes
that do not handle these types of property names correctly. The samples
included only show the results of ReflectionObject::getProperties(), but
also functions like ReflectionObject::hasProperty() incorrectly returns
false, for example.
Reproduce code:
---------------
<?php
$a = (object)array(1, 2, 3, 4);
echo '<pre>';
var_dump($a);
print_r($a);
var_export($a);
print_r(get_object_vars($a));
$r = new ReflectionObject($a);
print_r($r->getProperties());
?>
Expected result:
----------------
var_export($a);
output: stdClass::__set_state(array(1,2,3,4))
print_r(get_object_vars($a));
output: Array([0]=>1,[1]=>2,[2]=>3,[3]=>4)
print_r($r->getProperties());
output:
Array(
[0]=>ReflectionProperty Object (
[name]=>0
[class]=>stdClass
)
... and so on up to [3]
)
Actual result:
--------------
var_export($a);
output: stdClass::__set_state(array())
print_r(get_object_vars($a));
output: Array()
print_r($r->getProperties());
output:
note: this result varies
ie1:
Array
(
[0] => ReflectionProperty Object
(
[name] => â.C6ßÔXlé¤Ðø*ºv\ì#II
[class] => stdClass
)
[1] => ReflectionProperty Object
(
[name] => M ¨¾FÏXlé¤Ðø
[class] => stdClass
)
)
ie2:
Array
(
[0] => ReflectionProperty Object
(
[name] => F7¯5h¡ þoMWM=[*"ùI
[class] => stdClass
)
)
