SNMP::getnext

(PHP 5 >= 5.4.0, PHP 7)

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

说明

public SNMP::getnext ( mixed $object_id ) : mixed

Fetch an SNMP object that follows specified object_id.

参数

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

返回值

Returns SNMP objects requested as string or array depending on object_id 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

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);?>

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
)

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();?>

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
)
