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.
object_idThe SNMP object (OID) or objects
Returns SNMP objects requested as string or array
depending on object_id type or FALSE on error.
Esse método não lança nenhuma exceção por padrão.
Para ativar o lançamento de exceções SNMPException quando algum erro ocorrer,
o parâmetro exceptions_enabled
deve ser configurado. Veja
SNMP::$exceptions_enabledessa explicação para mais detalhes.
Exemplo #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);
?>
O exemplo acima irá imprimir algo similar à:
OID: NET-SNMP-MIB::netSnmpAgentOIDs.8
Array
(
[SNMPv2-MIB::sysObjectID.0] => OID: NET-SNMP-MIB::netSnmpAgentOIDs.8
)
Exemplo #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();
?>
O exemplo acima irá imprimir algo similar à:
Array
(
[SNMPv2-MIB::sysObjectID.0] => OID: NET-SNMP-MIB::netSnmpAgentOIDs.8
[SNMPv2-MIB::sysLocation.0] => STRING: Nowhere
)
