PHP - Manual: SNMP::getnext

2024-12-23

SNMP::getnext

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

SNMP::getnextFetch an SNMP object which follows the given object id

说明

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

Fetch an SNMP object that follows specified objectId.

参数

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.

错误/异常

本方法默认不抛出任何异常。如果要在某些库出错时抛出 SNMPException 异常,用户需要将 SNMP 类参数 exceptions_enabled 设定为相应的值。更多细节见 SNMP::$exceptions_enabled 的解释

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);
?>

以上例程的输出类似于:

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();
?>

以上例程的输出类似于:

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