Description: GET_META_TAGS returns an array which is not traversible by the EACH function

The returned array from a get_meta_tags call seems be doubled up.
A count on the array is double the amount of metatags.
I'm not too certain if it's a feature or a bug.

The HTML File being parsed contains
-----------------
<meta name="dc.title" content="The University of Queensland Home Page1">
<meta name="DC.date.issued" content="1998-12-15">
<meta name="DC.date.modified" content="1998-12-15">
<meta name="DC.type" content="document">
<meta name="DC.format" content="text/html">
<meta name="DC.identifier" content="http://www.uq.edu.au/">
<meta name="UQ.function" content="">
<meta name="UQ.recordtype" content="Home">
-----------------

The script processing the above file
-----------------

$test = get_meta_tags($url);

$num = Count($test);
$i=0;

echo "The Array contains $num Entries<BR><BR>";
ksort($test);
while ($results = each($test)){
        echo $i.":".$results["key"]." -- ".$results["value"]."<BR>";
        $i++;
}

------------------

The Resulting output
------------------
The Array contains 16 Entries
