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

### Description

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

Fetch an SNMP object that follows specified `object_id`.

### Parameters

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

### Return Values

Returns SNMP objects requested as string or array depending on `object_id` type or `FALSE` on error.

### Errors/Exceptions

This method does not throw any exceptions by default. To enable throwing an SNMPException exception when some of library errors occur the SNMP class parameter `exceptions_enabled` should be set to a corresponding value. See `SNMP::$exceptions_enabled` explanation for more details.

### Examples

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);
?>`

The above example will output something similar to:

    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();
?>`

The above example will output something similar to:

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