SNMP::get

(PHP 5 >= 5.4.0)

SNMP::getFetch an SNMP object

Beschreibung

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

Fetch an SNMP object specified in object_id using GET query.

Parameter-Liste

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.

object_id

The SNMP object (OID) or objects

preserve_keys

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.

Rückgabewerte

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

Fehler/Exceptions

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.

Beispiele

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.

<?php
  $session 
= new SNMP(SNMP::VERSION_1"127.0.0.1""public");
  
$sysdescr $session->get("sysDescr.0");
  echo 
"$sysdescr\n";
  
$sysdescr $session->get(array("sysDescr.0"));
  
print_r($sysdescr);
?>

Das oben gezeigte Beispiel erzeugt eine ähnliche Ausgabe wie:

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

Beispiel #2 Miltiple SNMP objects

$session = new SNMP(SNMP::VERSION_1, "127.0.0.1", "public");
  $results = $session->get(array("sysDescr.0", "sysName.0"));
  print_r($results);
  $session->close();

Das oben gezeigte Beispiel erzeugt eine ähnliche Ausgabe wie:

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