# snmpwalkoid

(PHP 3 >= 3.0.8, PHP 4, PHP 5)

snmpwalkoid -- Query for a tree of information about a network entity

## Descrição

array snmpwalkoid ( string hostname, string community, string object_id [, int timeout [, int retries]] )

snmpwalkoid() function is used to read all object ids and their respective values from an SNMP agent specified by `hostname`.

The existence of snmpwalkoid() and snmpwalk() has historical reasons. Both functions are provided for backward compatibility. Use snmprealwalk() instead.

## Parâmetros

`hostname`

  The SNMP agent.

`community`

  The read community.

`object_id`

  If `NULL`, `object_id` is taken as the root of the SNMP objects tree and all objects under that tree are returned as an array.

  If `object_id` is specified, all the SNMP objects below that `object_id` are returned.

`timeout`

`retries`

## Valores de retornado

Returns an associative array with object ids and their respective object value starting from the `object_id` as root or `FALSE` on error.

## Exemplos

Exemplo 1. snmpwalkoid() Example
`<?php $a = snmpwalkoid("127.0.0.1", "public", ""); for (reset($a); $i = key($a); next($a)) { echo "$i: $a[$i]<br />\n"; } ?>`

Above function call would return all the SNMP objects from the SNMP agent running on localhost. One can step through the values with a loop
