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 an 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.
Throws an SNMPException if a library error occurs
and its type is included in the SNMP::$exceptions_enabled bitmask.
Otherwise, emits an E_WARNING.
Example #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);
?>Il precedente esempio visualizzerà qualcosa simile a:
OID: NET-SNMP-MIB::netSnmpAgentOIDs.8
Array
(
[SNMPv2-MIB::sysObjectID.0] => OID: NET-SNMP-MIB::netSnmpAgentOIDs.8
)
Example #2 Multiple 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();
?>Il precedente esempio visualizzerà qualcosa simile a:
Array
(
[SNMPv2-MIB::sysObjectID.0] => OID: NET-SNMP-MIB::netSnmpAgentOIDs.8
[SNMPv2-MIB::sysLocation.0] => STRING: Nowhere
)
