SNMP::getnext — Fetch an SNMP object which follows the given object id
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.
objectIdThe SNMP object (OID) or objects
Returns SNMP objects requested as string or array
depending on objectId type or false on error.
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.
Örnek 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);
?>Yukarıdaki örnek şuna benzer bir çıktı üretir:
OID: NET-SNMP-MIB::netSnmpAgentOIDs.8
Array
(
[SNMPv2-MIB::sysObjectID.0] => OID: NET-SNMP-MIB::netSnmpAgentOIDs.8
)
Örnek 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();
?>Yukarıdaki örnek şuna benzer bir çıktı üretir:
Array
(
[SNMPv2-MIB::sysObjectID.0] => OID: NET-SNMP-MIB::netSnmpAgentOIDs.8
[SNMPv2-MIB::sysLocation.0] => STRING: Nowhere
)
