SNMP::getnext — Fetch an SNMP object which follows the given object id
$object_id
)
Fetch an SNMP object that follows specified object_id
.
If object_id
is a string, then SNMP::getnext()
will return SNMP object as string. If
object_id
is a array, all requested SNMP
objects will be returned as associative array of the SNMP object ids and their
values.
object_id
The SNMP object (OID) or objects
Returns SNMP objects requested as string or array
depending on object_id
type or FALSE
on error.
本方法默认不抛出任何异常。如果要在某些库出错时抛出 SNMPException
异常,用户需要将 SNMP 类参数 exceptions_enabled
设定为相应的值。更多细节见
SNMP::$exceptions_enabled
的解释。
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 )
