SNMP::getnext — Fetch an SNMP object which follows the given object id
$objectId
) : array|bool
Fetch an SNMP object that follows specified objectId
.
If objectId
is a string, then SNMP::getnext()
will return SNMP object as string. If
objectId
is a array, all requested SNMP
objects will be returned as associative array of the SNMP object ids and their
values.
objectId
The SNMP object (OID) or objects
Returns SNMP objects requested as string or array
depending on objectId
type or false
on error.
Esse método não lança nenhuma exceção por padrão.
Para ativar o lançamento de exceções SNMPException quando algum erro ocorrer,
o parâmetro exceptions_enabled
deve ser configurado. Veja
SNMP::$exceptions_enabled
essa 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 )
