SNMP::getnext()

(PHP 5 >= 5.4.0, PHP 7)

Fetch an SNMP object which follows the given object id

说明

publicSNMP::getnext(mixed $object_id): mixed

Fetch an SNMP object that follows specified$object_id.

参数

If$object_idis a string, then SNMP::getnext() will return SNMP object as string. If$object_idis 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_idtype 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
)
