SNMP::getFetch an SNMP object


public mixed SNMP::get ( mixed $object_id [, bool $preserve_keys = false ] )

Fetch an SNMP object specified in object_id using GET query.


If object_id is a string, then SNMP::get() 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.


The SNMP object (OID) or objects


When object_id is a array and preserve_keys set to TRUE keys in results will be taken exactly as in object_id, otherwise SNMP::oid_output_format property is used to determinate the form of keys.


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


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


Beispiel #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.

= new SNMP(SNMP::VERSION_1"""public");
$sysdescr $session->get("sysDescr.0");
$sysdescr $session->get(array("sysDescr.0"));

Das oben gezeigte Beispiel erzeugt eine ähnliche Ausgabe wie:

STRING: Test server
    [SNMPv2-MIB::sysDescr.0] => STRING: Test server

Beispiel #2 Miltiple SNMP objects

$session = new SNMP(SNMP::VERSION_1, "", "public");
  $results = $session->get(array("sysDescr.0", "sysName.0"));

Das oben gezeigte Beispiel erzeugt eine ähnliche Ausgabe wie:

    [SNMPv2-MIB::sysDescr.0] => STRING: Test server
    [SNMPv2-MIB::sysName.0] => STRING: myhost.nodomain
