SNMP::getnext — Fetch an SNMP object which follows the given object id
Fetch an SNMP object that follows specified object_id.
If object_id is a string, then SNMP::getnext() will return SNMP object as string. If object_id is a array, all requested SNMP objects will be returned as associative array of the SNMP object ids and their values.
The SNMP object (OID) or objects
Returns SNMP objects requested as string or array depending on object_id type or FALSE on error.
Example #1 Single SNMP object
Single SNMP object may be requested in two ways: as string resulting string return value or as single-element array with associative array as output.
<?php
$session = new SNMP(SNMP::VERSION_1, "127.0.0.1", "public");
$nsysdescr = $session->getnext("sysDescr.0");
echo "$nsysdescr\n";
$nsysdescr = $session->getnext(array("sysDescr.0"));
print_r($nsysdescr);
?>
The above example will output something similar to:
OID: NET-SNMP-MIB::netSnmpAgentOIDs.8 Array ( [SNMPv2-MIB::sysObjectID.0] => OID: NET-SNMP-MIB::netSnmpAgentOIDs.8 )
Example #2 Miltiple SNMP objects
<?php
$session = new SNMP(SNMP::VERSION_1, "127.0.0.1", "public");
$results = $session->getnext(array("sysDescr.0", "sysName.0"));
print_r($results);
$session->close();
?>
The above example will output something similar to:
Array ( [SNMPv2-MIB::sysObjectID.0] => OID: NET-SNMP-MIB::netSnmpAgentOIDs.8 [SNMPv2-MIB::sysLocation.0] => STRING: Nowhere )
