SNMP::getnext

(PHP 5 >= 5.4.0)

SNMP::getnext — Fetch an SNMP object which follows the given object id

Description

mixed SNMP::getnext ( mixed $object_id )

Fetch an SNMP object that follows specified object_id.

Parameters

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.

object_id: The SNMP object (OID) or objects

Return Values

Returns SNMP objects requested as string or array depending on object_id type or FALSE on error.

Errors/Exceptions

This method do not throw any exceptions by default. To enable throwing an SNMPException exception when some of library errors occure user should set exceptions_enabled SNMP class parameter to corresponding value. See SNMP->exceptions_enabled explanation for more details.

Examples

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();
?>
