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.
本方法默認不拋出任何異常。如果要在某些庫出錯時(shí)拋出 SNMPException
異常，用戶(hù)需要將 SNMP 類(lèi)參數 exceptions_enabled
設定為相應的值。更多細節見(jiàn)
SNMP::$exceptions_enabled 的解釋。
示例 #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);
?>
以上例程的輸出類(lèi)似于：
OID: NET-SNMP-MIB::netSnmpAgentOIDs.8
Array
(
[SNMPv2-MIB::sysObjectID.0] => OID: NET-SNMP-MIB::netSnmpAgentOIDs.8
)
示例 #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();
?>
以上例程的輸出類(lèi)似于：
Array
(
[SNMPv2-MIB::sysObjectID.0] => OID: NET-SNMP-MIB::netSnmpAgentOIDs.8
[SNMPv2-MIB::sysLocation.0] => STRING: Nowhere
)
