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_id
The SNMP object (OID) or objects
Returns SNMP objects requested as string or array
depending on object_id
type or FALSE
on error.
Această metodă nu emite careva excepții în mod implicit.
Pentru a activa emiterea unei excepții SNMPException când au loc erori în
bibliotecă trebuie stabilită o valoare corespunzătoare a parametrului clasei
SNMP exceptions_enabled
. Vedeți
explicația
SNMP::$exceptions_enabled
pentru mai multe detalii.
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);
?>
Exemplul de mai sus va afișa ceva similar cu:
OID: NET-SNMP-MIB::netSnmpAgentOIDs.8 Array ( [SNMPv2-MIB::sysObjectID.0] => OID: NET-SNMP-MIB::netSnmpAgentOIDs.8 )
Example #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();
?>
Exemplul de mai sus va afișa ceva similar cu:
Array ( [SNMPv2-MIB::sysObjectID.0] => OID: NET-SNMP-MIB::netSnmpAgentOIDs.8 [SNMPv2-MIB::sysLocation.0] => STRING: Nowhere )
