SNMP::getnext

(PHP 5 >= 5.4.0, PHP 7, PHP 8)

SNMP::getnext — Fetch an SNMP object which follows the given object id

說明

public SNMP::getnext(array|string $objectId): mixed

Fetch an SNMP object that follows specified objectId.

參數(shù)

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.

objectId

The SNMP object (OID) or objects

返回值

Returns SNMP objects requested as string or array depending on objectId type or false on error.

錯誤／異常

本方法默認不拋出任何異常。如果要在某些庫出錯時拋出 SNMPException 異常，用戶需要將 SNMP 類參數(shù) exceptions_enabled 設定為相應的值。更多細節(jié)見 SNMP::$exceptions_enabled 的解釋。

范例

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();
?>

以上例程的輸出類似于：

Array
(
    [SNMPv2-MIB::sysObjectID.0] => OID: NET-SNMP-MIB::netSnmpAgentOIDs.8
    [SNMPv2-MIB::sysLocation.0] => STRING: Nowhere
)
