too long

Question

I have a php script that is attempting to get a specific piece of data. I am using the snmprealwalk function but the page is not returning anything.

<?php
$a = snmprealwalk("192.168.107.130", "public", ".2.6.1.2.1.33.6.5.1.2.2.1"); 
for (reset($a); $i = key($a); next($a)) {
    echo "$i: $a[$i]<br />
";
}
?>

I know there is data there because if I simply take out the long iso_ID I will get all the data. This data contains the key or iso_ID I need to call a specific value.

How do I call a specific object_id using the php and snmp functions? What am I doing wrong? I am using php 5.3.28.
