SNMP::getnext
(PHP 5 >= 5.4.0)
SNMP::getnext — Fetch an SNMP object which follows the given object id
Description
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
)
