The snmpgetnext() function is used to read the
value of the SNMP object that follows the specified
object_id.
hostThe hostname of the SNMP agent (server).
communityThe read community.
object_idThe SNMP object id which precedes the wanted one.
timeoutThe number of microseconds until the first timeout.

Example #1 Using snmpgetnext()
<?php
$nameOfSecondInterface = snmpgetnetxt('localhost', 'public', 'IF-MIB::ifName.1';
?>
with snmpget api, the agent returns the value associated
with the OID (or OIDs) specified in the original request.
The snmpgetnext api is similar, but the agent returns the
value associated with the next (valid) OID
eg:
snmpgetnext('192.168.40.134',
'public',
'SNMPv2-MIB::sysUpTime.0');
will give the output:
STRING: user@hostname
