The answer should be an array with one text entry "INTEGER: 68", like in
snmpget, not an empty array.
You can test with an easier OID 1.3.6.1.2.1.2.2.1.8.3 (it is the state
of interface #3). In this case, the answer should be an array with one
string entry
["IF-MIB::ifOperStatus.3"]=>
string(14) "INTEGER: up(1)"
like you can see it if you test snmpwalk with 1.3.6.1.2.1.2.2.1.8
