# SNMP::get

(PHP 5 >= 5.4.0)

SNMP::get — Fetch an SNMP object

### Descrição

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

Fetch an SNMP object specified in `object_id` using GET query.

### Parâmetros

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.

### Valor Retornado

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

### Erros

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.

### Exemplos

Exemplo #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);
?>`

O exemplo acima irá imprimir algo similar à:

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

Exemplo #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();`

O exemplo acima irá imprimir algo similar à:

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