Description:
------------
When using a variant (e.g. new VARIANT(3)) as an index for an array, it generates "Warning: Illegal offset type".  I looked around and not sure if this is a bug or is expected behavior, but the only way to get around it is to convert the variant into an integer (e.g  sprintf).  

In addition, print_r of the variant returns "variant Object #" as explained in PHP Bug #35956.  Bug #35956 states that downloading the latest PHP solves the issue, however, the issue is still seen with the latest php version.

Reproduce code:
---------------
<?php

$v = new VARIANT(3);
print "The value is " . $v . "<br/>";

$arry = array("first","second","third","fourth","fifth");
echo $arry[$v] . "<br/>";  // This does not work

echo print_r($v) . "<br/>";  // This does not work

$v = 3;
echo $arry[$v]. "<br/>";  // This works

$v = new VARIANT(3);
echo $arry[sprintf($v)];  // This works

?>

Expected result:
----------------
The value is 3
fourth
fourth
fourth
fourth

Actual result:
--------------
The value is 3
