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

Description

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.

Parameters

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

Return Values

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

Examples

Example #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
