(PHP 4, PHP 5, PHP 7, PHP 8)

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

Description

snmpwalkoid(
    string $hostname,
    string $community,
    array|string $object_id,
    int $timeout = -1,
    int $retries = -1
): array|false

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
The number of microseconds until the first timeout.
retries
The number of times to retry if timeouts occur.

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
