SNMP::getnext

(PHP 5 >= 5.4.0, PHP 7, PHP 8)

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

Description

public function SNMP::getnext(array|string $objectId): mixed

Fetch an SNMP object that follows specified objectId.

Parameters

If objectId is a string, then SNMP::getnext() will return SNMP object as string. If objectId is an array, all requested SNMP objects will be returned as associative array of the SNMP object ids and their values.

objectId: The SNMP object (OID) or objects

Return Values

Returns SNMP objects requested as string or array depending on objectId type or false on error.

Errors/Exceptions

Throws an SNMPException if a library error occurs and its type is included in the SNMP::$exceptions_enabled bitmask. Otherwise, emits an E_WARNING.

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 Multiple 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();
?>
