Hi,
Sorry for embedding huge scripts into the report.
I submit you the new test code with open and close tags :
<?php
$stdclass = neW StdcLaSs() ;
$stdclass->{0} = 'index0' ;
$stdclassElement = (arRaY)$stdclass ;
$var = array_keys( $stdclassElement ) ;
$key = $var [ 0 ] ;
Echo
'$stdclassElement[ $key ] :: ' , $stdclassElement[ $key ] ,
'$stdclassElement[0] :: ' , $stdclassElement[ 0 ] ,
'$stdclassElement["0"] :: ', $stdclassElement['0']
;
?>
Hope it's gonna be more useful.
Do I have to submit the bug again under a new Id or it's gonna be find
like that ?
Regards,
Xavier

Here is a minimal test case:
<?php
$obj = new stdClass();
$obj->{0} = 'foo';
$obj->{'1'} = 'bar';
$obj->{'x'} = 'baz';
$array = (array)$obj;
var_dump($array[0]);
var_dump($array['1']);
var_dump($array['x']);
?>
Expected result:
---------------
string(3) "foo"
string(3) "bar"
string(3) "baz"
Actual result:
--------------
NULL
NULL
string(3) "baz"
If you compare var_dump((array)$obj) as defined above with
var_dump(array(0 => 'foo', '1' => 'bar', 'x' =>
'baz')), you can see
that the numeric array keys are stored as strings rather than
integers, which causes the array lookups to fail.
(PS: The above developer's response reads like a standard copy/paste
reply that ignores the fact that example code was already supplied. If
the example was insufficient or unclear, at least take 5 seconds to
explain why. The way this bug report is now, it does not help anyone.)

Description:
------------
object numeric's name properties are cast in string array's index.
created indexes becomes not accessible.
Reproduce code:
---------------
#5.2.7.-DEV on 2007-06-24
# WANTED => cast object to array and access first element with 0 index
#RESULT => the array key with the index '0' is nor accessible by 0 or
"0", uncool ...
#¿PROBLEM? => Shouldn't the array key needs to be numeric instead of a
string after object to array cast ?
$stdclass = neW StdcLaSs() ;
$stdclass->{0} = 'index0' ;
$stdclassElement = (arRaY)$stdclass ;
$var = array_keys( $stdclassElement ) ;
$key = $var [ 0 ] ;
Echo
'$stdclassElement[ $key ] :: ' , $stdclassElement[ $key ] ,
'$stdclassElement[0] :: ' , $stdclassElement[ 0 ] ,
'$stdclassElement["0"] :: ', $stdclassElement['0']
;
Expected result:
----------------
acess neither to array index '0' by [0] or ["0"]
Actual result:
--------------
the index is not accessible
