snmpwalk -- Fetch all the SNMP objects from an agent

## Description

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

Returns an array of SNMP object values starting from the object_id as root and `FALSE` on error.

snmpwalk() function is used to read all the values from an SNMP agent specified by the hostname. Community specifies the read community for that agent. A `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.

`<?php $a = snmpwalk("127.0.0.1", "public", ""); ?>`

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

`<?php foreach ($a as $val) { echo "$val\n"; } ?>`
