You are right! Don't know why I thought that would work. Guess I need to
sleep a bit.

@felipecg00:
1) yes, this happens only with numeric indexes
2) in your second snippet you are creating an empty
object and then assigning new element instead of modifying existing one.
Dump your
initial object in the beginning to see what I mean.

I can reproduce it in 5.3.3.
Seems like it happens with numeric indexes only:
//create object
$obj->q = 'something';
//convert object to array
$arr = (array)$obj;
//modify element
$arr['q'] = 'something else';
//dump final array
print_r($arr);
Result:
Array
(
[q] => something else
)
This way works:
//create object
$obj = new stdClass(array(
1 => 'something'
));
//convert object to array
$arr = (array) $obj;
//modify element
$arr[1] = 'something else';
//dump final array
print_r($arr);
Results:
Array
(
[1] => something else
)

Description:
------------
After converting and Object to an associative Array using (array)
variable type
prefix cannot access and modify existing elements.
Tested in all latest PHP versions with and without modules.
Test script:
---------------
//create object
$obj->{1} = 'something';
//convert object to array
$arr = (array)$obj;
//modify element
$arr[1] = 'something else';
//dump final array
print_r($arr);
Expected result:
----------------
Array ( [1] => something else )
Actual result:
--------------
Array ( [1] => something [1] => something else )
------------------------------------------------------------------------
