Description:
------------
Many people have complained about the indexed array bug already. Will this bug 
ever be fixed?

The keys are lost if they have a numeric value even if they are set to type 
string.

There was said that it wont be fixed:
http://bugs.php.net/21949
http://bugs.php.net/37746

There was said that it was fixed:
http://bugs.php.net/50285
http://phpxmlrpc.sourceforge.net/news.html

However it wasn't fixed. I still have the problem on PHP 5.3.1.

Test script:
---------------
<?
$a=array(1=>'one', '3'=>'three', 5=>'five', 'a'=>'foo');
print_r($a);
print_r(xmlrpc_decode(xmlrpc_encode($a)));
?>

Expected result:
----------------
Array
(
    [1] => one
    [3] => three
    [5] => five
    [a] => foo
)
Array
(
    [1] => one
    [3] => three
    [5] => five
    [a] => foo
)

Actual result:
--------------
Array
(
    [1] => one
    [3] => three
    [5] => five
    [a] => foo
)
Array
(
    [0] => one
    [1] => three
    [2] => five
    [a] => foo
)
