Description:
------------
Test script works, as expected, under PHP4.  Gives nonsensical error under PHP5.

Test script:
---------------
<?php
$registry = new COM('winmgmts:root/DEFAULT:StdRegProv');
$values = new VARIANT();
echo $registry->getBinaryValue(0x80000002,
'SOFTWARE\\Microsoft\\Cryptography\\RNG', 'Seed', $values);
var_dump($values->value);
?>

Expected result:
----------------
From PHP4:

$variant->type and $variant->value syntax is not supported in PHP5. See http://www.php.net/manual/en/class.variant.php for more details.

Doesn't seem like there is a way to print an array of variants in php5. Bug 35956 also talks about this problem.

Thank you for taking the time to write to us, but this is not
a bug. Please double-check the documentation available at
http://www.php.net/manual/ and the instructions on how to report
a bug at http://bugs.php.net/how-to-report.php

You can use foreach to iterate through variant array. See code below.

variant_get_type($values);
foreach($values as $value)
{
    echo ($value . "\n");
}
