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.

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