<?php
$session = new SNMP(SNMP::VERSION_1, "127.0.0.1", "public");
$sysdescr = $session->get("sysDescr.0");
echo "$sysdescr\n";
$sysdescr = $session->get(array("sysDescr.0"));
print_r($sysdescr);
?>

STRING: Test server
Array
(
[SNMPv2-MIB::sysDescr.0] => STRING: Test server
)
Przykład #2 Miltiple SNMP objects
$session = new SNMP(SNMP::VERSION_1, "127.0.0.1", "public");
