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.
This method does not throw any exceptions by default.
To enable throwing an SNMPException exception when some of library errors occur
the SNMP class parameter exceptions_enabled
should be set to a corresponding value. See
SNMP::$exceptions_enabled explanation for more details.
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
)
