Splitting an iptc array

[cmb]

I'll be creating a script that will get the keywords from uploaded pictures and what i cant figure out is how to actually get only the keywords from the iptc data this is the code i have for getting the iptc data right now:

<?php
$size = getimagesize('images/Sections/pinkpanthers/20102011/Session1/1-15-11/1.jpg', $info);
if(isset($info['APP13']))
{
    $iptc = iptcparse($info['APP13']);
    var_dump($iptc);
?>
}

and this outputs

array(4) { ["1#090"]=> array(1) { [0]=> string(3) "%G" } ["2#000"]=> array(1) { [0]=> string(2) "" } ["2#025"]=> array(1) { [0]=> string(5) "Tyler" } ["2#080"]=> array(1) { [0]=> string(15) "Christian" } }

all i want from the above string is the Tyler

$iptc['2#025'];

 

that index would be an array of all the keywords.  You can use that array however you wish.  Loop through it, implode it, whatever.
