SNMP::get

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

SNMP::get — Fetch an SNMP object

說明

public SNMP::get(array|string $objectId, bool $preserveKeys = false): mixed

Fetch an SNMP object specified in objectId using GET query.

參數(shù)

If objectId is a string, then SNMP::get() 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

preserveKeys

When objectId is a array and preserveKeys set to true keys in results will be taken exactly as in objectId, otherwise SNMP::oid_output_format property is used to determinate the form of keys.

返回值

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

錯(cuò)誤／異常

本方法默認(rèn)不拋出任何異常。如果要在某些庫出錯(cuò)時(shí)拋出 SNMPException 異常，用戶需要將 SNMP 類參數(shù) exceptions_enabled 設(shè)定為相應(yīng)的值。更多細(xì)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");
  $sysdescr = $session->get("sysDescr.0");
  echo "$sysdescr\n";
  $sysdescr = $session->get(array("sysDescr.0"));
  print_r($sysdescr);
?>

以上例程的輸出類似于：

STRING: Test server
Array
(
    [SNMPv2-MIB::sysDescr.0] => STRING: Test server
)

示例 #2 Multiple SNMP objects

$session = new SNMP(SNMP::VERSION_1, "127.0.0.1", "public");
  $results = $session->get(array("sysDescr.0", "sysName.0"));
  print_r($results);
  $session->close();

以上例程的輸出類似于：

Array
(
    [SNMPv2-MIB::sysDescr.0] => STRING: Test server
    [SNMPv2-MIB::sysName.0] => STRING: myhost.nodomain
)
