[2005-08-05 18:51 UTC] frymaster at linuxmail dot org

Description:
------------
in xml_wddx 1.0.1:

a string of numbers with a preceeding zero, ie. "0677", is automatically converted to type "number" at serialization, thus eliminating the zero.

the code that explicitly casts strings of digits to numbers is located on line 102 and reads:

if ( is_numeric ($value) && (intval(0+$value) == $value) )
return "<number>$value</number>";

this bug occurrs even if the string of digits is explicitly cast as a string prior to serialization.

Test script:
---------------
require_once "XML/Wddx.php";

$wddx_parser = new XML_Wddx();

$test_array = array((string)"098", (string)"0098", "0098R");

print_r($test_array);

$some_wddx = $wddx_parser->serialize($test_array);

print_r($some_wddx);

$back_test_array = $wddx_parser->deserialize($some_wddx);

print_r($back_test_array);

Expected result:
----------------
Array
(
[0] => 098
[1] => 0098
[2] => 0098R
)
<wddxPacket version='1.0'><header/><data>
<array length='3'>
<string>098</string>
<string>0098</string>
<string>0098R</string>
</array>
</data></wddxPacket>
Array
(
[0] => 098
[1] => 0098
[2] => 0098R
)

Actual result:
--------------
Array
(
[0] => 098
[1] => 0098
[2] => 0098R
)
<wddxPacket version='1.0'><header/><data>
<array length='3'>
<number>098</number>
<number>0098</number>
<string>0098R</string>
</array>
</data></wddxPacket>
Array
(
[0] => 98 <- where are my zeroes?
[1] => 98
[2] => 0098R
)
