SNMP::getnextFetch an SNMP object which follows the given object id

Beschreibung

public SNMP::getnext ( array|string $objectId ) : array|bool

Fetch an SNMP object that follows specified objectId.

Parameter-Liste

If objectId is a string, then SNMP::getnext() will return SNMP object as string. If objectId is a 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

Rückgabewerte

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

Fehler/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.

Beispiele

Beispiel #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);
?>

Das oben gezeigte Beispiel erzeugt eine ähnliche Ausgabe wie:

OID: NET-SNMP-MIB::netSnmpAgentOIDs.8
Array
(
    [SNMPv2-MIB::sysObjectID.0] => OID: NET-SNMP-MIB::netSnmpAgentOIDs.8
)

Beispiel #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();
?>

Das oben gezeigte Beispiel erzeugt eine ähnliche Ausgabe wie:

Array
(
    [SNMPv2-MIB::sysObjectID.0] => OID: NET-SNMP-MIB::netSnmpAgentOIDs.8
    [SNMPv2-MIB::sysLocation.0] => STRING: Nowhere
)
