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
-
preserve_keys -
When
object_idis a array andpreserve_keysset toTRUEkeys in results will be taken exactly as inobject_id, otherwise SNMP::oid_output_format property is used to determinate the form of keys.
Значення, що повертаються

depending on object_id type or FALSE on error.
Помилки/Винятки
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.
Приклади
Приклад #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);
?>
Наведений вище приклад виведе щось подібне до:
STRING: Test server
Array
(
[SNMPv2-MIB::sysDescr.0] => STRING: Test server
)
Приклад #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();
Наведений вище приклад виведе щось подібне до:
