There is a BUG. And a major one.
The most interesting aspect of this bug is that the deserialization
works perfectly under Zend Development Environment (3.5.0) but does not
work under my Apache 2.50 /PHP5.0.2. I'm using Win2003.
But the problem isn't in Apache (it seems), because the same bug occurs
when I run my .php file with php.exe.
DO SOMETHING!!!

More info on my previous note.
Sample code:
-------------------------------------------------------------
<?
function SanitizeArray ($arr) {
if (!is_array($arr)) { return $arr; };
while (list($key,$val) = each($arr) ){
if (is_array($val)) { $val = SanitizeArray($val); };
$rtn[$key] = $val;
};
return $rtn;
};
$test = array(
0 =>array(
'me' => "you"
),
'one' => array(
'me' => "you"
)
);
print "<PRE>";
var_dump($test);
print $test[0]['me'] . "\n";
print $test['0']['me'] . "\n";
print $test['one']['me'] . "\n";
$ddx = wddx_serialize_vars("test");
$after = wddx_deserialize($ddx);
var_dump($after['test']);
print $after['test'][0]['me'] . "\n";
print $after['test']['0']['me'] . "\n";
print $after['test']['one']['me'] . "\n";
list($key,$val) = each($after['test']);
print gettype($key);
$clean = SanitizeArray($after);
var_dump($clean['test']);
print $clean['test'][0]['me'] . "\n";
print $clean['test']['0']['me'] . "\n";
print $clean['test']['one']['me'] . "\n";
list($key,$val) = each($after['test']);
print gettype($key);
print "</PRE>";
phpinfo();
?>

I am also having difficulty with deserialize.
If I take an array and run wddx_serialize_vars("thisarr"). Then take
the result and deserialize it, any array keys that are numbers produce
a "no such index" when dereferencing. I was able to work around the
problem with the following:
function SanitizeArray ($arr) {
if (!is_array($arr)) { return $arr; };
while (list($key,$val) = each($arr) ){
if (is_array($val)) { $val = SanitizeArray($val); };
$rtn[$key] = $val;
};
return $rtn;
};
array keys that were strings did not have any problems.

I experienced the same behaviour with php 5.0.1 running on
linux/apache.

Description:
------------
for exchanging a screenshot gallery i decode every exif information in
a wddx packet. worked without problems in php4.3.x under win32 and
linux.
now with php5.0.0, the wddx is generated proberly but cannot
deserialized. if i reduce the size of the hash, it works, but that is
not a solution. the error.log from apache shows nothing hintful.
Reproduce code:
---------------
1. the wddx generation
// save the cache file
$wddx = wddx_packet_start("Screenshots");
wddx_add_vars($wddx, "sort");
$wddx = wddx_packet_end($wddx);
$wddx = addslashes($wddx);
$file = $_cache."_includes/screenshots.wddx.php";
$fp = fopen($file, "w");
fwrite($fp, $wddx);
fclose($fp);
2. the deserialize process
// read wddx cache file
$wddx = file_get_contents($_cache."_includes/screenshots.wddx.php");
$wddx = stripslashes($wddx);
$wddx = wddx_deserialize($wddx);
$wddx = $wddx["sort"];
Expected result:
----------------
an array with the original hash
Actual result:
--------------
an empty result
